A regular pentagon is a 5-sided polygon with sides of equal length and interior angles. Its exterior angles are formed outside the pentagon when its sides are extended, and each angle is equal to 72°. The sum of all interior angles in a regular pentagon is equal to 360°, with each interior angle measuring 108° and each exterior angle measuring 72°.
A regular pentagon has 5 diagonals, with an area of approximately 1.7204774 × s2 (where s=side length). The sum of interior angles of any polygon is always 360 ∘. To find each of the exterior angles of a regular pentagon, divide 540° by the number of sides.
Examples of regular pentagon properties include side, diagonal, height, perimeter, area, circumcircle, and incircle radius. A regular pentagon has 5 angles that are all the same size, and the measure of each exterior angle is given as 360°/n = 360°/5 = 72°.
The sum of interior angles in a regular pentagon is 360°, with each interior angle measuring 180 – 108 = 72. The measure of each exterior angle of a regular pentagon is 72°, where n is the number of sides in the polygon. In a regular pentagon, the sum of all interior angles is equal to 540°, with each interior angle measuring 108° and each exterior angle measuring 72°.
