Identifying Complementary, Supplementary, Vertical, and Adjacent Angles

Deepen students' understanding of angles with this seventh-grade geometry worksheet! Students will learn or review the definitions of complementary, supplementary, vertical, and adjacent angles. Then they will have several opportunities to apply these definitions as they seek to identify the various angles contained within different images. Learning to identify complementary, supplementary, vertical, and adjacent angles is an important skill that will help students later solve problems with missing angle measures.
