Question

What is the measure of each exterior angle of a regular dodecagon?

• A. ${30}^{\circ }$
• B. ${60}^{\circ }$
• C. ${90}^{\circ }$
• D. ${40}^{\circ }$

Answer 1

The correct option is A ${30}^{\circ }$

The given polygon is a regular dodecagon.

A dodecagon has $12$ sides.

The sum of exterior angles of a polygon is ${360}^{\circ }$.

The measure of each exterior angle of a regular dodecagon will be $=\frac{{360}^{\circ }}{12}={30}^{\circ }$
