Fun Facts About Nonagons

One cool thing about a nonagon is that if all its sides and angles are the same size, it is called a regular nonagon. Each angle in a regular nonagon measures 140 degrees. Even though it might seem easy to draw, a perfect nonagon cannot be made using just a compass and straightedge. People use special tools to make it look almost perfect.

Nonagons also appear in music! The band They Might Be Giants has a happy song called “Nonagon” on their children's album _Here Come the 123s. The song is about a party with many-sided shapes and a fun dance.
