Heptagon facts for kids
A heptagon is a cool shape! It's a type of polygon that has 7 straight sides and 7 corners. You might also hear it called a septagon or a 7-gon.
What is a Regular Heptagon?
When a heptagon is "regular," it means all of its 7 sides are exactly the same length. Also, all of its 7 corners (or angles) are the same size. Each corner in a regular heptagon measures about 128.57 degrees. If you add up all the angles inside a regular heptagon, they total 900 degrees.
How to Find the Area
The area of a shape tells you how much flat space it covers. For a regular heptagon, you can find its area using a special math formula.
The formula looks like this:
In this formula, a stands for the length of just one of its sides. So, if you know how long one side is, you can figure out the total area!
