Understanding Angles: Supplementary and Complementary

The video tutorial explains how to identify angles that are supplementary and complementary to a given angle B. It describes the properties of supplementary angles, which sum to 180°, and complementary angles, which sum to 90°. The tutorial also covers how to calculate the measures of specific angles, such as angle EF and angle AOE, using properties like vertical angles and right angles. The video provides a step-by-step approach to understanding these concepts with examples.
