Exterior Angle Calculator

Exterior Angle Calculator

The Exterior Angle Calculator is a tool used to calculate the exterior angle of a polygon. An exterior angle is the angle formed by one side of a polygon and the extension of an adjacent side. It is helpful in geometry and trigonometry to determine the measurements and relationships between the angles of a polygon.


The formula for calculating the exterior angle of a polygon is: Exterior Angle = 360° / Number of Sides


If you have a pentagon with five sides, the exterior angle would be calculated as follows: Exterior Angle = 360° / 5 = 72°

This means that each exterior angle of the pentagon measures 72 degrees.
