The sum of all exterior angles of all polygons is \(360\degree\).
Also, in a regular polygon, each exterior
angle is of the same measure.
Hence, if \(360\degree\) is a perfect multiple of the given exterior angle, then the given polygon will be possible.
(a) Exterior angle = \(22\degree\)
\(360\degree\) is not a perfect multiple of \(22\degree\).
Hence, such polygon is not possible.
(b) Interior angle = \(22\degree\)
Exterior angle = \(180° - 22° = 158°\)
Such a polygon is not possible as 360° is not a perfect multiple of \(158°\)
