Given Transitive prop. congruence Definition of congruence Given Transitive prop. Equality/Substitution

Given Definition of complementary angles Given Congruent Complements Theorem

Given Definition of linear pair Linear pair postulate Congruent supplements theorem

Given Vertical angles congruence thm Transitive prop of congruence

Linear pair postulate tells us that a linear pair sums to 180 degrees

Vertical angle congruence theorem states that vertical angles are congruent. This means that they have the same angle measure.
