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.
Continue ReadingThe 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. All regular pentagons have an area that can be calculated by multiplying the square of the length of an individual side by the constant 1.72.
