To find the sum of the interior angles for any polygon use (n-2)*180 degrees where n is the number of sides.

## What is the interior angle of a regular n sided polygon?

Angles. degrees, with the sum of the exterior angles equal to 360 degrees or 2π radians or one full turn. As the number of sides, n approaches infinity, the internal angle approaches 180 degrees. For a regular polygon with 10,000 sides (a myriagon) the internal angle is 179.964°.

## What is the formula for interior angles?

An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n – 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.
