Question Analysis

This question involves the characteristics of regular polygons. The main focus is on understanding how to find the measure of an interior angle of a regular polygon based on the number of its sides.

Key Concept Explanation

The sum of the interior angles of a polygon is given by the formula , where is the number of sides of the polygon. For a regular polygon, all interior angles are equal. So, to find the measure of one interior angle, we divide the sum of the interior angles by the number of sides .

Step - by - Step Solution
