So, the sum of the interior angles of a heptagon is 900 degrees. Regular Heptagons: The properties of regular heptagons: All sides are the same length (congruent) and all interior angles are the same size (congruent).

In this regard, what is a convex hexagon?

Equivalently, it is a simple polygon whose interior is a convex set. In a convex polygon, all interior angles are less than or equal to 180 degrees, while in a strictly convex polygon all interior angles are strictly less than 180 degrees.

Why is it called a Heptagon?

A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning "seven") with the Greek suffix -gon (from gonia, meaning "angle"), and is therefore not recommended.

What is a convex and concave polygon?

Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
