Unit 3
Constructions and Angles

# Unit Description

By folding paper, you'll explore how you can think about angles and figures. Then you will learn about types of angles—adjacent, supplementary, complementary, and vertical—and how they are manifested in quadrilaterals. Using that knowledge, you will look at triangles and their properties, including the angle sum, and how this affects other figures. Then you will solve equations to find unknown angle measures.
