Quadrilaterals and Polygons

Polygons are an important class of geometric shapes. In this unit students study the hierarchy of polygons from the most general to very special quadrilaterals. They extend both interior and exterior angle sum theorems to general polygons, manipulate segments to create quadrilaterals, and investigate properties of special quadrilaterals.
