        Measurement and Geometry | Angles: Complementary and Supplementary

        Understanding complementary and supplementary angles will help you solve for an unknown angle measurement. If the measure of two angles added together equals 90o, the angles are complementary. A supplementary angle is formed when the sum of the measures of two angles equals 180o.

        These resources are part of KET's Measurement and Geometry collection.
