# What is the sum of the interior angles of a convex Heptagon?

CcoolmathUpdated: 2nd October 2019

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**.
