POLYGONS

What is a Polygon?

A closed figure made by joining line segments, where each line segment intersects exactly two others

Examples of polygons:

What is Not a Polygon

This figure is not a polygon because it is not a closed figure.

More About Polygons

You can describe a polygon by comparing: The lengths of

its sides OR The measures

of its angles

Describing Polygons

Equilateral

Equiangular

Regular

All the sides of the polygon are congruent

All the angles of the polygon are congruent

The polygon is both equilateral and equiangular
