Complementary and Supplementary Angles

This video tutorial covers the concepts of complementary and supplementary angles, which are pairs of angles with specific sum properties. Complementary angles sum to 90 degrees, while supplementary angles sum to 180 degrees. The video provides definitions, illustrations, and examples of each type of angle pair. It also includes problem-solving exercises to help viewers apply these concepts. The tutorial concludes with an activity for viewers to engage with the material and encourages interaction through comments.
