Geometry Section 1.5 Describe Angle Pair Relationships

Complementary Angles Two angles whose sum of their measures is 90°

Supplementary Angles Two angles whose sum of their measures is 180°

Adjacent Angles Two angles that share a common vertex and side, but have no common interior point.

Linear Pair Two adjacent angles are a linear pair if their noncommon sides are opposite rays. The angles in a linear pair are supplementary angles

Vertical Angles Two angles are vertical angles if their sides form two pairs of opposite rays
