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

(i) 170°

(ii) 138°

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

(i) 80°

(ii) 40% of a right angle

The exterior angle of a regular polygon is one third of its interior angle. Find the number of sides in the polygon.

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
