Up coming freshmen

Hello my fellow bloggers!
This is a special occasion! I am coming back for one more blog to give all the incoming freshmen tips on high school. So if you are going into high school this is the blog for you!
1. Don't be afraid to ask for help. The teachers are nice, they want to help, and they will if you ask.
2. Don't procrastinate. Things can be harder than they seem and if you save it until last minute, you will stay up until 2:30am. When you fall behind, you REALLY fall behind.
3. Study DAYS before finals and midterms. If you save it until the day before, you won't get any sleep.
4. I advise getting two backpacks, one for blue days and one for white days (If your school does this). This makes it easier. You can keep all your binders and books in one backpack, no switching things in and out everyday.
5. Don't stop in the middle of intersections or the long hallways when there are tons of people in the hallway. People don't like it when you block the hallways.
6. Get to lunch early. If you buy hot lunch all the good stuff will be gone if you wait too long.
7. Walk fast.They will run you over.
8. Join sports or clubs, it's a good way to meet new friends (especially upperclassmen, which is always good(: ).
9. Find the fastest route to your classes. It helps when you're running a little late.
10. Take classes you want to take. If you take classes to be with your friends, the chances are you're not going to be in the same class anyway.
Okay, now I'm serious, this is my last blog. I hope you enjoyed my little tips! Have fun new high schoolers!
Your favorite blogger, Livy.

Review Question 2/Goodbye!

Hello again! Today, I am posting another review question. This comes from chapter 5.
Question: Which of they following is the concurrent point of the altitudes?
Answer: Orthocenter.
I always remember which concurrent point goes with which line of a triangle because of MAPA COCI.
MAPA COCI stands for:
Median --> Centroid
Altitude --> Orthocenter
Perpendicular Bisector -->Circumcenter
Angle Bisector --> Incenter
This helped me remember and hopefully it will help you too! :)
Now down to the sad stuff. :( I won't be saying 'see you next week' anymore..... because this is my last blog! *Gasp* I hope my blogs have helped you in some way or another, but right now I have to say goodbye for good. I know you'll miss me though!
Farewell, Livy

Review Question

Our final exam is Wednesday! Ahhh! And in preparation to that I am going to be posting a review question from one of the chapters we learned about this semester.
In chapter 7 we learned more about areas of formulas. My review question today, will be finding the area of a rhombus (remember that the diagonals of a rhombus bisect each other). The formula for an area of a rhombus is 1/2(d1+d2), d stands for diagonal.
If your given information was that one diagonal was 7cm and half of the other diagonal was 5.5cm, this is how you would solve it:
We know that the other half of the diagonal is 5.5cm, because it gets bisected from the other diagonal.
Now we plug in our given information to come up with 1/2(7+11) = area. Simplify to get 1/2(18) = area.
Now simply multiply by 1/2 or divide by two, and we get 9cm squared = area
Hopefully this helped you! I will be posting another review question soon! Goodbye!

SOH, CAH, TOA?

What are these words?? What do they mean?!
Well, they are ways to remember the sine, cosine, and tangent rules. To get the Sine of an angle you have to divide its Opposite side length by the Hypotenuse side length, SOH. Sine = Opp/Hyp. To get the Cosine of an angle you have to divide its Adjacent side length (not the hypotenuse) by the Hypotenuse, CAH. Cosine = Adj/Hyp. To get the Tangent of an angle, you divide its Opposite side length by its Adjacent (not the hypotenuse) side length, TOA. Tangent = Adj/Opp.
Well, this is what we learned about in class this week. I'll blog next week about more! See you in 7 days!

Area Formulas

So how was everybody's week? Mine was good! This weekend has been amazing! Finally the weather has been nice! It reached 80º today! Yay!
Anyway.. we learned more about formulas, for areas of shapes. We learned the areas for parallelograms (bh), triangles (1/2bh), circles (pi: 3.14 times radius squared), kites/rhombi (1/2diameter times diameter), trapezoids (1/2 height(b1+b2)), regular polygons (1/2apothem times perimeter), sectors (arc measure/360 times pi: 3.14 times radius squared), and segments (rc measure/360 times pi: 3.14 times radius squared - 1/2bh). There was a lot of memorizing in this chapter.
My favorite formula is the parallelogram formula, because it's simple and easy and we have been using it since kindergarten. My least favorite is the segment formula. It's very complicated and long. Short and sweet is the way to go!
See ya in 7 days! Have a nice week everybody!

Special Right Triangles

Last week I talked about the 30º-60º-90º theorem and the 45º-45º-90º theorem. This week I'm going to talk about them a little more in-depth.
When you are dealing with a 45º-45º-90º triangle, the hypotenuse is √2 times any side. When you are dealing with a 30º-60º-90º triangle the hypotenuse is 2 times the short side, while long side is √3 times the short side. I remember which theorem is which by thinking of the side lengths. In a 45º-45º-90º triangle, there are two different side lengths, so the hypotenuse is √2 times the short side. In a 30º-60º-90º triangle there are 3 different side lengths, so the long side is √3 times the short side. This helped me, so maybe it can help you!
See you next week my fellow bloggers!

Pythagorean Theorem

This week in geometry we starting using the pythagorean theorem. We are using this theorem to help find the missing third side in a triangle. This is my first time using the pythagorean theorem and I actually understand it! I though I wasn't gong to be abe too, but I do! I was surprised by the fact that the pythagorean theorem can actually tell you if the triangle is acute, obtuse, or a right triangle!
We also learned more about the specialties of a right triangle, mostly the theorems that go along with right triangles. Like the 45º-45º-90º theorem and the 30º-60º-90º theorem, which are definitely going to come in handy when I only have 5 minutes left on a test....
And that's what happened this week in geometry! I'll fill you in next week!

Radicals

This week in geometry we had a "quest" about transformations. It was a quiz, but counted for 100 points, like a test. We were also introduced to radicals. We previously learned radicals last year in algebra, so we were re-introduced. For me, radicals are relatively easy. What I mean by this, is that I can do all of them except the fractions that have one square and one integer. These are confusing to me :/
In other news, it was the first week back from April vacation...Yay? I'll have to think on that one. I also started lacrosse on Friday! Yay! I'm not fully participating, but I can go to the practices and do the conditioning. Good enough for me! I just missed going to practice and being with my lax buddies(:
This week was a good week for me and hopefully there will be more! See you next week!

Reflections

Well Howdy there! I haven't been able to post on the computer in a while!...It feels good to be back. Ahhhh.
So anyway, this week in geometry we learned about rotations and more on reflections. We also started working on our scratch projects. The scratch projects seem to be going good. The program can just be a little confusing at times. Reflections are easy most of the time, but they can also be quite hard. I haven't quite mastered them yet.
So this weekend is the start of APRIL VACATION! Wahooooo! It couldn't have come at a better time than this! The weather has been so beautiful! It is perfect for the beach!
And now it's time for that depressing part when my blog is nearing the end. Talk to you guys after vacation! Ciao!

Four Day Week Again!

Another four day week! With this snow day today, we are going to have 3 weeks of 4 day school weeks in a row! I definitely have no problem with that!
I and very grateful for this snow day today because I got to study for biology and english! For biology I started the 122 question packet for the midterms. Blahh, I only got to question 9...... For english I studied for the vocabulary quiz. And the one thing I am having trouble with is just that, finding time. With hockey almost everyday, and having tests and quizzes everyday this week, I have had barely anytime to study for the midterms next week! Hopefully finals won’t be this bad, but I have a bad feeling they will be. Ugh.
The one problem I have studied for the most would be proofs. I know how to do them, but I just blank on the reasons why on tests and quizzes. Sometimes they are ones that I have no clue how to solve them, so I'm those to make sure I know how to this time.
Well see you next time amigos!...When midterms are over!
