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?

1. 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.

2. Next, calculate the exterior angle.

Using the formula, we find the exterior angle to be 360/6 = 60 degrees.
