Interior Angle of a Regular Pentagon

Very Easy Geometry Polygons

Consider a regular polygon with 5 sides, also known as a pentagon. A regular polygon is defined as a polygon with all sides of equal length and all angles of equal measure. To find the measure of each interior angle of a regular polygon, you can use the formula:

$${ ext{Interior Angle}} =\frac{(n - 2) imes 180^ ext{o}}{n}$$

where $n$ is the number of sides in the polygon. For this problem, determine the measure of each interior angle of a regular pentagon.
