what degrees does a polygon equal?
A polygon with five sides is called a pentagon. In Greek, pente means five.. When math textbooks discuss pentagons, they are typically referring to a polygon with five equal sides, otherwise known as a regular pentagon. The sum of all the angles inside of any polygon drawn on a flat surface is 540 degrees. In a regular pentagon, each angle has 108 degrees. In other pentagons, an individual angle cannot be more than 540 degrees or less than 0 degrees.
