Supplement Theorem If <1 and <2 form a linear pair, then m<1 + m<2 = 180.
Complement Theorem If the noncommon sides of two adjacemt angles form a right angle, then the angles are complementary angles.
If m<1 + m<2 = 180 and m<2 + m<3 = 180, then <1 = <2. Angles supplementary to the same angle or to congruent angles are congruent.
