Enter the total number of sides of a polygon into the calculator to determine the exterior angle. This calculate can also calculate the number of sides given the other variables.
Exterior Angle Formula
The following formula is used to calculate the exterior angle of a polygon.
A = 360 / N
- Where A is the exterior angle
- N is the number of sides of the polygon
To calculate the exterior angle, divide the 360 by the number of sides.
Exterior Angle Definition
An exterior angle is defined as the angle on the exterior of two tangent lines that extend past the sides of a polygon.
Exterior Angle Example
How to calculate an exterior angle?
- Fist, determine the number of sides.
Count the number of sides of the polygon being analyzed. For this example we will look at a hexagon that has six sides.
- Next, calculate the exterior angle.
Using the formula, we find the exterior angle to be 360/6 = 60 degrees.
An exterior angle is the angle measured between two tangent lines that extend off the sides of a polygon.
