THEOREMS Complement Theorem: If the
noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles.
PROPERTIES Reflexive Property: <1<1
Symmetric Property: <1 <2 then <2 <1
Transitive Property: If <1 <2 and <2 <3 then <1 <3
THEOREMS: Congruent Supplements Theorem:
Angles supplementary to the same angle or to congruent angles are congruent themselves.
