Angle Relationships and Properties

The video tutorial covers angle pair relationships, including complementary, supplementary, and vertical angles. It explains how complementary angles sum to 90 degrees, while supplementary angles sum to 180 degrees. Vertical angles are described as congruent when two lines intersect. The video includes a proof demonstrating the congruence of vertical angles and provides practice problems to reinforce the concepts.
