Complementary and Supplementary Angles

This video tutorial covers the concepts of complementary and supplementary angles. It explains that complementary angles sum up to 90 degrees, while supplementary angles sum up to 180 degrees. The video provides examples and exercises to help understand these concepts, including solving for unknown angles. The tutorial concludes with a summary and motivational message.
