Types of Polygons:

**Regular Polygon**: All sides are equal

**Triangle**: 3 sided polygon

**Square or Rectangle**: 4 sided polygon

**Pentagon**: 5 sided polygon

**Hexagon**: 6 sided polygon

**Heptagon**: 7 sided polygon

**Octagon**: 8 sided polygon

**Nanogon**: 9 sided polygon

**Decagon**: 10 sided polygon

**Dodecagon**: 12 sided polygon

In this lesson, we will learn how to sort polygons by:

All sides are equal

All sides are not equal

At least 1 right angle

At least 1 set of parallel sides

Lesson 5 Homework

1. Match the polygons with their appropriate clouds. A polygon can match to more than 1 cloud.

2. The two polygons below are regular polygons. How are these polygons the same? How are they different?

3. Lucia draws the polygons below. Are any of the polygons she drew regular polygons? Explain how you know.

Examples:

1. Define the following polygons.

2. Sort the following polygons.
