Interior Angles of a Regular Pentagon

Very Easy Geometry Polygons

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

$$(n - 2) \times 180^\circ$$

where $n$ is the number of sides. For a pentagon, calculate the measure of each interior angle.
