Exploring Complimentary and Supplementary Angles

This lesson covers complementary and supplementary angles, exploring how geometry helps describe real-world objects. It discusses the application of angles in bridge construction, explains key concepts of complementary and supplementary angles, and provides examples and guided problems to identify angle pairs and solve for missing measures. The lesson concludes with a word problem to reinforce understanding.
