Given Transitive prop. congruence Definition of congruence Given 5. 5. 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.
