1. 2.3 Complementary and Supplementary Angles

2. Complementary Angles: Two angles are complementary if the sum of their measures is 90 0. Complement: The sum of the measures of an angle and its complement is 90 0 Supplementary Angles: Two angles are supplementary if the sum of their measures is 180 0 Supplement: The sum of an angle and its supplement is 180 0 Adjacent Angles: Two angles are adjacent angles if they share a common vertex and a ray, but have no common interior points Theorem: A theorem is a true statement that follows from other true statements
