The central angle of a n-sided regular polygon = 360 degrees / n. Hence, the central angle of a 15-sided regular polygon = 360 degrees / 15 = 24 degrees ============================

Whether you are talking about the measure of each interior angle, or the total of all the interior angles, there is no largest. The more sides a regular polygon has, the larger it angles will be. As the number of sides grows without bound, the measure of each interior angle gets closer and closer to 180 degrees, and the polygon looks more and more like a circle. The sum of the interior angles increases by 180 degrees every time you add a side.
A regular hexagon.
As the number of sides in a regular polygon increases, the angle increases. This occurs as a function where each interior angle measures (180*(n-2)) / n, where n is the number of sides.
Each central angle is (360) divided by (number of sides in the polygon).

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.
the center angle of any polygon is 360 degrees
