**Unit 7: Quadrilaterals and Transformations**

**CONCEPT...PROPERTIES OF FIGURES ON A COORDINATE GRID**

*Essential Questions*

What are the relationships among parallelograms and non-parallelograms?

How do you translate, rotate and reflect quadrilaterals and triangles about a coordinate plane?

*In this unit, we study the properties of quadrilaterals and circles. Your first task is to complete a regular pentagon, hexagon and octagon using oragami.*

**5.1: Polygon Sum Conjecture examples for class**

**5.2: Exterior Angles of a Polygon**

*Examples:*

*1. How many sides does a regular polygon have if each exterior angle is 18?*

*2. How many sides does a polygon have if the sum of the measures of the interior angles is 3420?*

*3. If the sum of the interior angles of a polygon are three times the sum of it's exterior angles, then how many sides does the polygon have?*
