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°.
In your exam, you might be asked to find angles of polygons. The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) Ã 180Â° where n is the number of sides of the polygon. This formula comes from dividing the polygon up into triangles using full diagonals. We already know that the interior angles of a triangle add up to 180Â°.
