Exploring Supplementary Angles and Their Relationships

The video tutorial explains supplementary angles, which are angles that add up to 180 degrees. It provides examples of solving for unknown angles in supplementary pairs, including both simple and complex problems. The tutorial also covers how to identify supplementary angles in images by recognizing intersecting lines and straight lines.
