Theorems: Right Angles Congruence Theorem All right angles are congruent Vertical Angles Congruence Theorem Vertical angles are congruent. Congruent Supplements Theorem If then two angles are supplementary to the they are congruent. same angle (or to congruent angles), are supplementary & are supplementary Congruent Complements Theorem If then two angles are complementary to they are congruent. the same angle (or to congruent angles), are complementary & are complementary Linear Pair Postulate If then two angles form a linear pair, they are supplementary.
