Complementary and Supplementary Angles

The video tutorial explains how to use a tool to understand complementary and supplementary angles. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. The tutorial demonstrates how to calculate missing angles by using addition and subtraction, providing examples for both types of angles. It also briefly touches on more complex angle problems, which will be covered in future lessons.
