POLYGON ANGLE CALCULATOR

The calculator given in this section can be used to know the name of a regular polygon for the given number of sides. 

And also, we can use this calculator to find sum of interior angles, measure of each interior angle and measure of each exterior angle of a regular polygon when its number of sides are given.   

Formulas : 

The sum of the measures of the interior angles of a convex n-gon is

(n - 2) ⋅ 180°

The measure of each interior angle of a regular n-gon is

1/n ⋅ (n - 2) ⋅ 180°

or

[(n - 2) ⋅ 180°]/n

The sum of the measures of the exterior angles of a convex polygon, one angle at each vertex is

360°

The measure of each exterior angle of a regular n-gon is

360°/n
