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
