A regular polygon with each interior angle measuring 120 degrees is a hexagon.

If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.

The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.

It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line

Providing that it's a regular polygon each interior angle is: 1520 18' 27.69''
