The measure of one exterior angle of a regular 18-gon is 20°. The sum of all exterior angles of a regular polygon is always 360° so the measure of each exterior angle can be calculated by dividing 360° by the number of sides. In this case that would be:
- 360° 18 = 20°
Therefore the measure of one exterior angle of a regular 18-gon is 20°.
