This Math Shorts video reviews different types of angles: complementary, supplementary, adjacent angles and then explains how to find unknown angles.

This video was made for the PBS Learning Media library, thanks to a generous grant from the Corporation for Public Broadcasting. It was produced in collaboration with Utah Education Network.

Common Core State Standards:
CCSS.Math.Content.7.G.B.5 (Grade 7): Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
