Best Answer

The sum of the interior angles of any polygon can be determined by using the formula (n-2)180, where n=the number of sides of that polygon.

For example, you can calculate the sum of the interior angles of a polygon with five sides (a pentagon):

(n-2)180

(5-2)180

3x180

540

So, the sum of the interior angles of a pentagon is 540.
