A pentagon is a flat shape with 5 straight sides and 5 corners. It has 5 straight sides and 5 corners. Below you will find its properties, how to draw it, where to spot it in real life, and a quick quiz.

A bright pentagon for little learners to explore!
| Sides | 5 straight sides |
|---|---|
| Corners (vertices) | 5 |
| Angles | Each angle is 108 degrees in a regular pentagon (540 degrees in total) |
| Lines of symmetry | 5 (in a regular pentagon) |
| Flat or solid | Flat (2D) |
A pentagon has 5 straight sides and 5 corners. 'Penta' means five. In a regular pentagon, all the sides are the same length and every inside corner measures 108 degrees. If you join each corner of a pentagon to the corners that are not next to it, you draw a five-pointed star inside it.
You can spot the pentagon shape in everyday life, like a home plate in baseball, a school crossing sign, and the U.S. Pentagon building. Try going on a shape hunt around your house or classroom — how many pentagons can you find today?

Send children on a hunt for pentagon shapes — a crossing sign, home plate on a diagram, a picture of the Pentagon building — and gather the finds on a table. Then play a matching game: draw several shapes on cards and have kids sort out only the pentagons.
Draw a square and add a triangle "roof" on top to build a simple house-shaped pentagon, then count all 5 sides together. It's an easy trick that turns two familiar shapes into a new one.
Point out that home plate in baseball is a pentagon — ask your child why its shape (a square with a pointed back) helps umpires and players judge exactly where a pitch crosses.
