## What is the formula to find the measure of each interior angle of a regular polygon?

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.

## What is the formula of sum of interior angles?

Interior and exterior angle formulas: The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180. If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.

## Which of the following is a formula to find the sum of interior angles of a quadrilateral of N sides?

The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides.

## What is the measure of each interior angles of a regular dodecagon?

And there are twelve angles… So, the measure of the interior angle of a regular dodecagon is 150 degrees.

## What is the measure of each interior angle of a regular 10 Gon?

Decagon Definitions A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440° .

## What is the sum of the measures of the interior angles of a regular 18 Gon?

A polygon with 18 sides has an interior angle sum of 2880 degrees.
