# What is the angle of Heptagon?

To find the measure of the interior angles, we know that the sum of all the angles is 900 degrees (from above) And there are seven angles So, the measure of the interior angle of a regular heptagon is about 128.57 degrees.

### What is the shape of a Heptagon?

A polygon is an enclosed two-dimensional shape with straight sides. This includes triangles, quadrilaterals, pentagons, etc but not circles or ovals. A heptagon is a seven-sided polygon. Along with seven sides, a heptagon has seven vertices and angles.
• #### What is the shape of a hexagon?

Shapes for kids: Hexagons. The hexagon is a six sided polygon. Each side must be closed and the shape not only needs six sides to qualify as a hexagon, but it must have six angles.
