What is the measure of an exterior angle of a dodecagon?
Exterior angles of dodecagon measure
Exterior angle of a dodecagon (12-sided regular polygon) is supplementary to its interior angle.
Sum of all interior angles of
Therefore, sum of interior angles of
All 12 interior angles of dodecagon are equal, so each is
A supplementary exterior angle, therefore, equals to
For a regular
Since a dodecagon has
