what is the interior angle of a regular polygon

http://www.mathsisfun.com/geometry/interior-angles-polygons.html

the sum of all the exterior angles of an n-gon

= 180(n-2)
but there are n of these, so each one is
180(n-2)/n°

The interior angle of a regular polygon can be calculated using the formula:

Interior Angle = (n-2) * 180 / n

Where "n" represents the number of sides in the regular polygon. To find the interior angle, you need to know the number of sides the polygon has.

For example, let's say you have a regular hexagon, which has 6 sides. Using the formula, you can calculate:

Interior Angle = (6-2) * 180 / 6
= 4 * 180 / 6
= 720 / 6
= 120

Therefore, the interior angle of a regular hexagon is 120 degrees.

If you know the number of sides of the regular polygon, you can use the formula to calculate the interior angle.
