its interior angles add up to 3 Ã 180Â° = 540Â°. And if it is a regular pentagon (all angles the same), then each angle is 540Â° / 5 = 108Â°. (Exercise: make sure each triangle here adds up to 180Â°, and check that the pentagon's interior angles add up to 540Â°) The Interior Angles of a Pentagon add up to 540Â°.
The number of triangles which compose the polygon is two less than the number of sides (angles). We generalize this result for a polygon of n sides and angles: Theorem: The sum of the interior angles in a polygon with n sides is 180Âº(n â 2). In the pentagon below, we have labeled the interior angles 1, 2, 3, 4, and 5.
