Each central angle of a regular 9 sided polygon: 360/9 = 40 degrees
360 degrees ( all the way round the central point). However, for one given sector it is 360/12 = 30 degrees.
This figure is a regular 12-sided polygon. Find m<4
The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.

To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.
Each central angle of a regular 9 sided polygon: 360/9 = 40 degrees
It can have any value at all. A definite value can be determined if the polygon is regular, but there is no justification for assuming that to be the case.
Each central angle is (360) divided by (number of sides in the polygon).
Each interior angle of a regular 10 sided decagon measures 144 degrees
