Complementary and Supplementary Angles Explained

This video tutorial introduces complementary and supplementary angles, explaining their definitions and properties. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. The video provides examples of both adjacent and non-adjacent angles for each type. It also includes problem-solving exercises to find missing angle measures using equations, reinforcing the concepts of complementary and supplementary angles.
