Exploring Angle Relationships Vocabulary

The video tutorial introduces angle relations, focusing on key vocabulary such as complementary, supplementary, adjacent, and vertical angles. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. Adjacent angles are next to each other, and vertical angles are congruent angles across an intersection. The tutorial includes examples and encourages students to take notes and practice identifying these angle relationships.
