Greetings everyone! This is my last geometry blog before finals. I have my geometry final the last day of school and I think this is a good thing because it gives me more time to study and review. I started reviewing for finals more than a month ago so I feel pretty confident I will do well. I just think it will be hard to remember what we learned back in September. Ultimum vale omnes.

Salutations fellow bloggers! This week in geometry class we learned about the law of sine and cosine. It isn't to difficult but I don't really understand how it saves you time.
My question for the final review is: What quadrilaterals have diagonals that bisect each other?
Answer: Parallelogram, rhombus, rectangle, and square
Have a great week everyone!

Sine, Cosine, Tangent

Greetings everyone. This week in geometry class we learned about sine, cosine, and tangent. These are formulas that an help me find the length of a side in a triangle by using an angle measure and a different side. These only work in right triangles. Each formula connects different sides and angle measures. To help remember which goes with which, I use SOH, CAH, and TOA. I find these acronyms very helpful and it will be interesting to see what we do next with these formulas. Thanks for reading my blog and check in next week to hear an update on what we learned in class.

Salutations fellow bloggers. Last math class I took a test on finding the area of parts of circles and triangles. It was horrible. It wasn't that the test was extremely hard, but it was just so long. Also, my geometry teacher wasn't there and I couldn't understand the wording of a few of the questions and I had no one to ask. I wasn't at class Tuesday because of a field trip and was sick the next day. This meant I didn't get a chance to have the questions I had on my homework answered. Over all, I don't feel confident I did well on this test. Thanks for reading and have a nice weekend.

Track Meet

Hello everybody! This past week was great. I had a track meet Friday and I won the 800m and placed second in the 1600m. My 4X400 relay team also won. It was lots of fun. The scratch project we have been working on for forever is due next week. The hardest part was trying to sync it to the music. I could make one tessellation and plan the entire program, but to see if it looks okay, I need to have all of them. After I've made all my pieces, if it's one second off, I need to go throughout and change the time on each piece. It takes forever! I can't wait to see everyone's projects next week.

Special Triangles

Greetings fellow bloggers! This week we learned about special triangles and ways to find their side lengths. The special triangles we learned about were right triangles with 60º and 30º angles and right triangles with two 45º angles. These shortcuts really help to speed up my work when finding the area of triangles. One thing I like about the shortcuts is they are not formulas, so I don't have to state my variables. Have a nice week!

Hey everyone, I had my first track meet Friday and it was really fun. I won the 800m and got 5th in the 1600m. I was also in the 4 X 400 meter relay for the first time.
In geometry we are learning about radicals. This confused me because I already learned about radicals but it was nice to review them before using them for bigger things. To help me simplify the square roots faster, I am memorizing my square roots up to 25. I'm using this sight to help me: http://quizlet.com/1136699/square-roots-to-25-flash-cards/
So far I have most of them memorized except a few of the harder ones. My goal is to have them memorized by the end of the week. I hope everyone has a good weekend.

I had a fantastic April vacation. I went horseback riding in the mountains; it was really fun. I also went out for dinner in Boston. In geometry we are still working on translations. They aren't very hard but I thought my homework over vacation was. It was on tessellations and I had a hard time seeing them. I also worked on my scratch project over vacation and it turned out pretty cool. I hope everyone enjoyed their vacation as much as me!

I hope everyone had a great Easter. I sure did! Not only was the long weekend helpful but I got to spend time with some of my family I hadn't seen in a while. I had an easter egg hunt with my family and found a chocolate bunny in a scavenger hunt. My Aunts and Uncles and I went out for brunch and Although the food wasn't very good, the deserts were yummy!
In geometry class last week we learn about translations. They aren't too hard but I still don't understand how they will help with the scratch project.
April vacation is coming up next week and I am so excited. I'm going to Connecticut to visit family and work. Everyone have a wonderful vacation and have fun!

Hello everyone, the quarter is almost over and we just completed our final geometry test. I thought I'd done well and I got a 94. I also got my grade back for the triangle poster, another big grade this term. I didn't do very well because my color coding wasn't clear enough. I never really understood what the color coding was supposed to be. I'm excited for next term and hope I get to do the scratch project. I hope everyone has a great next term!!

Quadrilaterals

Happy Sunday, I hope everyone had a great weekend. In geometry class, we are learning about quadrilaterals. I find a lot of the "rules" about them difficult to remember. I think we need to spend a class doing more practice. The sheet we had to do for class starter last class really let me know how much work I needed to do. I think we will move on to pentagons after quadrilaterals but most of the theorems are going to be based on it being made of three isosceles triangles. We also took a binder quiz and no matter how much time we get, I always have to rush through it. I wish everyone a wonderful week!

NWEA's

Greetings everyone. Last class we took the NWEA's for math. It took me the class period and half of lunch to finish but in the end I scored a 281. This is a really good score and I'm happy about it but what made me most proud was that I actually knew how to solve all the problems. Last fall I scored 280. This was really shocking for me because I thought I did a lot better than in the fall. Even though Ms. J said it would be mostly algebra, I found there were lots of geometric style problems. The things I learned this winter helped me on the test and I would have thought I'd improve. Hope everyone has a great week.

Hey everybody, last class we had a test on indirect proofs, coordinate proofs, lines in triangles and the points they intersect at. It was a pretty long test but most of the questions were multiple choice so it wasn't very hard. I think I did okay on it. My birthday last week was great. I got a trampoline from my parents and some sapphire earrings from my grandmother. The earrings were her mother's and are really pretty.
Bye everyone

Hello everyone! In geometry class this week we learned a new type of proof using indirect thinking. When we first started learning about them I thought they would be really hard, but they aren't as challenging as I thought they would be. I still don't like them because they involve a lot of writing but the indirect proofs enable us to solve proofs we couldn't solve before. This Wednesday we are having our test and because it is also my birthday, I think I might bring food into class.
Thanks for reading my blog!

Hello fellow bloggers, this week was vacation and I spent most of it skiing. It was really fun but I can't believe how fast the school year is going by. I guess it's just one of those years.
We just received a new triangle project that I worked on during vacation. I am almost finished but I keep on getting confused in the directions. I can't tell where I include just my line and where I have to do it for all the lines. Anyways, I used lots of color I it looks really cool. I was also wondering about the scratch project and when we are going to start it. We just talked about it and I haven't heard anything else in a while. I hope everyone had a great vacation and I'll see you in school.

Coordinate Proofs

Hey everybody. Last class we took a test on coordinate proofs and the lines in triangles. It was one of the easier tests we have taken this year, and I hope I did well.
In this unit, we used the lines in triangles and the coordinate proof method to find three new theorems. Now we are learning about the different centers triangles have based on the different lines. I think we will find theorems about the centers using coordinate proofs next. The coordinate proofs are my favorite so far because you don't have to justify your steps. I hope we will incorporate this method into our future curriculum.
Thanks for reading my blog.

Hello everyone. This week we were told we will have a project we need to do on Scratch. We needed to go an and explore the site. This was one of me favorite projects. http://scratch.mit.edu/projects/andre_pa/2234646
It is a cat that meows and walks around. You can also chose between two different backgrounds and control it using the arrows on the keyboard. I like it because I think the cat is really cute and this program is really cool.

Greetings everyone. This week is midterm week at our school and I was pleasantly surprised by my first midterm. They aren't really that hard or outrageous. They are more like really long tests. I haven't taken my geometry midterm yet, but I am glad its my last one. I get more time to study than any of the other classes. For studying, I found it helpful to go over old quizzes and tests. Also doing problems from the book helps. I go through and do a few problems from each chapter. Sometimes I don't even solve it. I just write down the steps I would need to go through to solve it and make sure I know how. Thanks everyone and good luck.

Hello everybody! Last class we learned a bunch of new theorems and corollaries about isosceles triangles. They let us prove that if two of the angles are congruent or if two of the side lengths are congruent, it is an isosceles triangle. The next theorem we learned told us that the vertex angle bisector is perpendicular to the base. We also had a quiz about the triangle theorems and how to prove triangles congruent. Coming up are midterms and I am really nervous. We have learned a lot this year and it will be hard to remember it all.

My favorite Postulate

Hey guys. In this blog I want to tell you about my favorite postulate. My favorite postulate is the corresponding angles postulate. I like it because it lets us use so many other theorems and helps in finding angle measures and proving lines parallel. It is very use full and as with all postulates, I wonder who thought of this. Did some man spend his whole life measuring the corresponding angles of parallel lines? I will never know.

My Favorite Problem

My favorite problem was question one on the honors geometry in class review. I really liked it because it involved factoring and angle pairs. I think factoring is really cool and also a little fun. The answer to this problem is x=5 or x=1/2. It was interesting to be able to connect angle pairs with the factoring. I used to get very confused with factoring and how there could be two answers but now I think they are easy. I like using them for problems.

Hello everyone, we just took a test last class on polygons. I hope I did okay on it because I don't feel we spent a lot of time on them. I finished my golf project this weekend and am happy to have finished it. It was really fun and I liked making it. It came out very nice. I still need to write the reaction part though and I'm not excited to do that.

Hello bloggers, I am so excited there are only 21 days till Christmas! We got assigned a mini-golf project this term. I am really excited to do something creative again. This project sounds really fun. I am not anticipating the writing part though, and it is going to be hard to make the ball bounce at least six times before getting in the hole. I have decided to do a rainbow theme for my project. It will be really cool, but I haven't decided if I want it to be two stories or only one.

Classifying Triangles and New Theorem
Article posted November 28, 2011 at 12:23 AM GMT •
comment • Reads 96

Thanks in advance to all bloggers who read. In this blog I am going to discuss the new theorem and term I learned when dealing with triangles. In geometry class, we learned about the exterior angles of a polygon. I thought the relationship they had with the other two nonadjacent angles of a triangle is pretty interesting. I knew that they had a special relationship but I wasn't sure what it was. I think this theorem is going to be helpful with other polygons because lots of them are made up of triangles: two triangles in a quadrilateral, three triangles in a pentagon.....
We also learned about classifying triangles and I learned the new and not entirely useful term equiangular. This wasn't useful because if a triangle is equilateral, it is also equiangular.

My Opinion on Proofs

For all my co-bloggers, I would like to share my opinion on proofs. We have been making proofs in geometry class for the last couple weeks. So far, we have learned to make the paragraph proofs and the table proofs. Out of the two, I like the table proofs best because they are easier. At first proofs were confusing and I always missed a lot of steps, but now I understand them, and they aren't really that hard. The key was to start with what I knew and list every step it took to prove something. It helped for me to plan out what my steps were going to be so I didn't use any extra steps. I hope this helped anyone who might of had trouble with proofs.

Supplementum—something added to supply a deficiency

Hello bloggers, this is my second blog and this on is about angle pairs. I found this cool math site that I wanted to share with all of you that talks about angle pairs.
http://www.onlinemathlearning.com/pairs-of-angles.html
The definition of angle pairs it uses is:
Any two angles that relate to each other in any way.
The pair I like the most are supplementary angles because they are so useful in finding missing angle lengths and so easy to identify. I remember what they are through a serise of steps. First I remember that complementary angles are one 90º part because the c has one curve. Second, I know that the s has two curves and is then two 90º parts or 180º. Next I see the two curves in the s as made up of two angles.
Hope you enjoyed learning about how I remember what the characteristics of a supplementary angle pair. While this works for me, it might not for you so I would suggest checking out this website and looking at the examples and finding coming up with one that does.

Good day fellow bloggers. This blog is about constructions and toward the end, I will give step by step instructions on my favorite construction.
A construction is drawing a shape using a straight edge and a compass without measuring angles or line segments.If you were wondering, my favorite construction is the perpendicular line from a point on that line because it seems the most useful out of all the constructions. It seems very useful when making squares or rectangles with right angles. It also is pretty easy to draw and I like how the arcs look like a fish when they intersect!
These are some step by step instructions if you would lie to make this construction.
1. Set your compass to any degree and put it on the point on the line. Draw an arc that intersects the line on both sides of the point keeping the degree the same.
2. Still keeping the degree the same, move the compass to the intersection of the line and the arc you just made. Draw an arc making sure it goes more than 180º.
3. Move the compass to the opposite intersection between the line and the first arc you made and keeping the degree the same, make a third arc, letting it intersect with the second arc.
4. Where your third and second arc intersect make a point.
5. Connect that point to the point on the line.
Please continue to check this blog if you would like to hear more about math.
