 Zack's Blogmetry This blog is for Miss Jovanovich's algebra and geometry classes to share ideas, ask questions, and reflect on what skills and topics we are studying. If we are lucky, we might even get a chance to connect with other students studying the same stuff.

To find the area of a trapezoid, the formula is Area=1/2(height)(base1+base2). So you will need to find the height and the length of both bases. So if one base was 6cm, the other 8cm, and the height 4cm, you would set up your equation like this: Area=1/2(4cm)(6cm+8cm)-->Area=2cm(14cm)-->Area=28cm squared. That is your answer.

The question as what is the point of rotation, and what is the angle of rotation. When given a pre-image and an image, to find the point of rotation, it will either be where the two images intersect or a point not connected to either image. Then to find the angle of rotation, you will need a protractor. Put your protractor on the point of rotation and pick a point you want to measure from. You always measure from the pre-image and counterclockwise unless stated to go clockwise. After you pick the point, find the point on the image that is the same, and measure. That will give you the angle of rotation Stay classy bloggers. Article posted June 10, 2012 at 10:32 AM GMT-5 • comment • Reads 214

Soh stands for sine=opposite side over the hypotenuse. That is the ratio for sine. Cah stands for cosine=adjacent side over the hypotenuse, which is also the ratio for cosine. And lastly, Toa stands for tangent= opposite side over the adjacent side. That is the ratio for tangent. Soh-Cah-Toa is used so people like me can think of it and remember the ratios quickly without needing to check my binder. That is what we are learning geometry right now. Have a great short week everyone. Stay classy bloggers. Article posted May 29, 2012 at 06:15 AM GMT-5 • comment • Reads 48

I have had 3 quizzes and 2 tests. Also, I have had 2 big projects this week as well. That is a lot of grades going into the grade book. So onto geometry. We just took geometry test on area theorems. My favorite area theorem is the parallelogram are theorem. A=bh. They can be easy, but also can be difficult. If the parallelogram is not a rectangle and you don't have the height, they become harder. It is my favorite because they are easy and fun. Thank you for tuning in. Talk to you next week blogmeisters. Article posted May 20, 2012 at 05:33 PM GMT-5 • comment • Reads 29

One would use the Pythagorean theorem to find the lengths of the sides of a right triangle. The formula is: leg1 squared + leg2 squared = hypotenuse squared. The hypotenuse is the side opposite the right angle. There are two special triangles when using the Pythagorean theorem. There is the 45 degree-45 degree right triangle, and there is the 30 degree-60 degree right triangle. In the 45-45 right triangle, the hypotenuse = the leg times root 2. In the 30-60 right triangle, the hypotenuse = the short leg times 2, and the long leg = the short leg times root three. Well have a great week bloggers, stay classy.

When dealing with radicals, it is a very good idea to know all the square roots to at least 20. If you ever forget them, you can look back on here. The square root of 1 = 1 The square root of 4 = 2 The square root of 9 = 3 The square root of 16 = 4 The square root of 25 = 5 The square root of 36 = 6 The square root of 49 = 7 The square root of 64 = 8 The square root of 81 = 9 The square root of 100 = 10 The square root of 121 = 11 The square root of 144 = 12 The square root of 169 = 13 The square root of 196 = 14 The square root of 225 = 15 The square root of 256 = 16 The square root of 289 = 17 The square root of 324 = 18 The square root of 361 = 19 The square root of 400 = 20 That is all the square roots to 20. Have a great week. Stay classy bloggers! Article posted April 29, 2012 at 02:59 PM GMT-5 • comment • Reads 44
 Article posted April 22, 2012 at 05:57 PM GMT-5 • comment • Reads 33 I hope everyone's vacations have been a blast! Mine has been fun. I played a lot of sports. I played a lot of tennis in DC, basketball on Thursday, golf on Friday and Saturday, then soccer today. We had a great soccer game today even though it ended in a 0-0 tie. In geometry, we are continuing to practice our skills with translations. The four translations are rotations, dilations, translations, and reflections. My favorite transformation is translation because I can do them quickly. My least favorite transformation is rotations because they are the most time consuming and I like problems that are quite quick to answer. I do find that all of the transformations come easily to me, as I hope they do for everyone else. Have a great week. Until next time, stay classy bloggers!

My family usually goes to our cousin's house for a get together, but it was called off this year. Instead, we went out to brunch in Exeter with my grandparents. It was nice. It was at the Exeter Inn. I have found ease with the transformations given to our class so far. I don't find them too hard to create. We have done translations, reflections, and dilations so far. We still have rotations to learn, and I believe we are learning those tomorrow in class. My favorite translation to this point would have to be reflections. Reflections create an image that mirrors the pre-image using the line of reflection. I just find them the most fun to do. 3/4 of the year done, 1/4 to go! Check in next week. Be courteuos my bloggers. Until next week... Article posted April 8, 2012 at 08:57 PM GMT-5 • comment • Reads 36

The people that need those couple of points to get their final grade where they want it and the ones right on the edge of a grade they want, like me, are all hoping they did very well on this last test. I did infact feel really good after taking this test. I feel that I am going to raise my grade a little after this test, I hope. I hope everyone gets the grade they want! On to quarter 4. Check back in next week. Stay classy bloggers. Article posted March 30, 2012 at 08:05 AM GMT-5 • comment • Reads 55
 Article posted March 25, 2012 at 08:40 PM GMT-5 • comment • Reads 33 This past week has been amazing. The weather mostly in the high 70's, low 80's, and it's only March! This week, unfortunately, is supposed to cool down to around the 40's. Come on March! We were on a roll. The grades for our school close on this coming Friday for the quarter. Now is the time to make sure you get great grades on this week's homework, quizes, or tests. I believe that were are having another grade going into this quarter for geometry. That can be the make or break of some students grade. I have got to make sure that I get a good grade on it. Well I will keep you all updated. Stop by next week!
