Regular polygons have exterior angles which are all equal to each other.

Moreover they always add up to 360º.

To work out the size of each exterior angle of a regular polygon, we simply divide 360º by the number of angles.

The number of angles is equal to the number of sides.

 

Example

Work out the exterior angle of a regular hexagon.

 

Answer

The hexagon has 6 exterior angles as shown below.

 

 

 

They add to 360º.

 

Each exterior angle is 360º ÷ 6 = 60º
