Exploring Angle Pairs Vocabulary

This video tutorial covers various types of angle pairs in geometry, including complementary, supplementary, adjacent, and vertical angles. It explains the properties and characteristics of each type, using examples and diagrams. The tutorial also introduces key postulates and theorems, such as the linear pair postulate and the triangle sum theorem, providing a comprehensive understanding of angle relationships in geometry.
