Q5)

(a) Is it possible to have a regular polygon with measure of each exterior angle as 22°?

(b) Can it be an interior angle of a regular polygon? Why?

Solution 5:

(a): The sum of all exterior angles is 360,

A polygon will be possible 22 is proper multiple of 360

Since 22 is not a proper multiple of 360, the polygon wont be possible.

(b): Interior angle=22

Exterior angle=180-22

=158

Since 158 is not a proper multiple of 360 the polygon wont be possible.
