Answer:- The answer of this question is 900°. The angle sum of a 7 sided polygon(Heptagon) is 900°.

## What is a 7 sided shape called?

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.

## Does a heptagon have 7 sides?

A heptagon is a polygon that has seven sides. It is a closed figure having 7 vertices. A heptagon is also sometimes called Septagon.

## How many exterior angles does a heptagon have?
