# Interior Angles of Polygon Calculator

The measures of angle at the interior part of any enclosed shape are called as an interior angle. The sum of the Interior Angle and Exterior Angle is always 180°. Similarly the measures of angle at the interior part of any Polygon are called as an interior angle of polygon.

To calculate the sum of interior angles of the polygon we use the formula:
(a - 2) * 1800, where ‘a’ is the number of the sides of polygon.

Interior Angles of Polygon Calculator is a calculator that is used to calculate the sum of interior angles of polygon. Interior Angles of Polygon Calculator has text space to take input which is “number of sides” from the user side and a “solve” button which on clicking shows the result.

Steps to use Interior Angles of Polygon Calculator are:
Step 1:
Enter value of number of sides of the polygon.
Step 2: Click on ‘solve” button and we will get the result.

Let’s take an example to use Interior Angles of Polygon Calculator:
Step 1:
Enter value of number of sides of polygon as [5].
Step 2: Click on ‘solve’ button and we will get the result 540.
