Friendly Angles

Students continue to explore angle measurements and their relationships. They learn formal ways to describe two specific angle relationships: complementary angles and supplementary angles. They also revisit what they learned in Unit 6 as they connect angle diagrams to equations.  Note: This lesson includes a paper supplement.
