Complementary and Supplementary Angles

This video tutorial covers the concepts of complementary and supplementary angles, explaining how complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees. It provides practical examples and explores the application of these concepts in light refraction. The video concludes with a summary of key points.
