In geometry, a polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides. It does not have curved sides. The sides of a polygon are also called its edges. The points where two sides meet are the vertices (or corners) of a polygon. Here are a few examples of polygons.

Discover 7 free and ready-to-use GeoGebra resources for grades 4-8 to learn and practice naming polygons by the number of sides and differentiate between quadrilaterals based on their properties.
Watch a video. A polygon is regular if all of its sides have the same length and all of its angles have the same measure. The angles all measure 90 °. hatch marks indicate that the sides all have the same length. Questions. answered.
What are polygons? Polygons are enclosed 2D shapes with straight sides. Two sides of a polygon meet at a vertex. 2D polygons are flat, meaning they are plane figures. Here is an example of a polygon: Polygons have interior angles and exterior angles.
