Is it possible to have a regular polygon whose each exterior angle is:

(i) 80°

(ii) 40% of a right angle

Find the number of sides in a regular polygon, if its interior angle is equal to its exterior angle.

The measure of each interior angle of a regular polygon is five times the measure of its exterior angle. Find:

(i) measure of each interior angle,

(ii) measure of each exterior angle and

(iii) number of sides in the polygon

The ratio between the interior angle and the exterior angle of a regular polygon is 2 : 1. Find.

(i) each exterior angle of the polygon,

(ii) number of sides in the polygon.
