. Prove that is isosceles. This was the question I was given.
This is my work: is an altitude of . Therefore, it goes straight down from the vertex to be perpendicular with 
. is also a bisector of . Therefore, it cuts in half. Because cuts 
in half by going straight down perpendicular to 
, 
and 
are at the same angle to 
This means the triangle has two congruent angles, making it isosceles. (See Theorem 4.7 and Theorem 4.9).
