Interior Angles of a Regular Pentagon

Very Easy Geometry Polygons

Consider a regular pentagon. A regular pentagon is a five-sided polygon with all sides of equal length and all interior angles equal. The measure of each interior angle in a regular pentagon can be calculated using the formula:

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

where $n$ is the number of sides of the polygon. For a pentagon ($n = 5$), what is the measure of each interior angle?
