The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
Theorem 1: If two angles are each complementary to a third angle, then they are congruent to each other. In short, Complements of the same angle are congruent. Proof: Let $\angle$A and $\angle$B be complementary angles. Thus, $\angle$B is a complement of $\angle$A.
