### What is Meant by Interior Angles of Polygon?

When each pair of adjacent sides joined together, the angles inside the polygon are formed. It is known as interior angles of a polygon. To find the interior angles of a polygon, follow the below procedure.

- Note down the number of sides “n.”
- To find the interior angles of a polygon, use the formula,

Sum of interior angles = (n-2)×180° - To find each interior angle of a polygon, then use the general formula,

Each angle of regular polygon = [(n-2)×180° ] / n - Substitute the given side value in the formula to get the solution.
