In this lesson, students learn about four types of angles: adjacent, vertical, supplementary, and complementary. They explore the relationships between these types of angles by folding paper, measuring angles with a protractor, and exploring interactive sketches. Included are examples, discussion questions, and challenge problems. Interventions are given for ELL students.
