Geometry: Angles and Relationships

This video tutorial covers the concepts of parallel lines and transversals, focusing on angle pairs such as vertical angles, linear pairs, and special angle pairs like alternate interior, alternate exterior, corresponding, same side interior, and same side exterior angles. The video explains the relationships between these angles when lines are parallel and demonstrates how to solve algebraic problems involving these angles. The tutorial concludes with challenge problems to reinforce the concepts learned.
