Hello everyone! I can't believe we're already eight days into the year 2012! Time really does fly, and with midterms coming up, I wish it would slow down a little.
As you know, my geometry class has been learning a lot about triangles in this unit. This past week we went over isosceles triangles, which are triangles that have two sides of equal length. Specifically, we worked with theorems and corallaries about them. For example, we learned the Isosceles Triangle Theorem, which states that if two sides of a triangle are congruent, then the angles opposite those sides (base angles) are congruent. We also learned the Hypotenuse Leg Theorem, which states that if the hypotenuse and a leg of one right triangle are congrunet to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
Since we've also had to complete a lot of proofs this unit, I'm really excited to have the knowledge of these new theorems and corollaries. They'll really help me shorten my proofs!
Hope this information about isosceles triangles has been helpful! Have a fantastic week! :)
