Exploring Complementary and Supplementary Angles

This video tutorial covers the concepts of complementary and supplementary angles. It explains that complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. The video provides examples using right triangles and linear pairs, and includes practice problems to reinforce understanding. Advanced problems are also discussed, focusing on angle relationships and solving systems of equations. The tutorial concludes with a summary of the key concepts.
