 Emma's Extravagant Blog 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.

Problem from Chapter 3 Good Evening Everyone! It is time for us to bid farewell to Chapter 3 considering that we took our test today and are now moving on to the next chapter. Personally, I enjoyed chapter 3 because learning all of the postulates and theorems helped me to gain a new understanding on angles and corresponding parts, as well as polygons. One of my favorite problems from chapter 3 was this; Triangle RGT is a right triangle. Angle G is a right angle and angle R=19 degrees. Find the measurement of angle T.
It takes a few steps to solve this problem. First of all, you have to remember that a right triangle is equal to 90 degrees due to the Definition of a Right Triangle. Next you have to remember that the sum of all the angles in a triangle will add up to 180 degrees due to the Triangle Angle-Sum Theorem. Therefore, if you add the two measurements of the angles that you have together and subtract them from 180, then you will get the measurement of the missing angle. For example, 90+19=109, and 180-109=71. Therefore, the measurement of angle T is equal to 71 degrees.
I enjoyed this problem because it was similar to a puzzle that you have to solve in order to get the answer. It also relates to triangles, and I found that I really enjoyed working with triangles during this chapter! What was your favorite problem?
