Angle Relationships and Properties

The video tutorial covers angle relationships, including congruent, vertical, adjacent, complementary, and supplementary angles. It explains how to measure angles using a protractor and solve equations involving angles. The lesson emphasizes understanding the properties of different angle types and provides examples to illustrate these concepts.
