A regular polygon: A polygon having all sides of equal length and the interior angles of equal size is known as regular polygon.
(i) 3 sides
Polygon having three sides is called a triangle.

(ii) 4 sides
Polygon having four sides is called a quadrilateral.

(iii) 6 sides
Polygon having six sides is called a hexagon.

### How many sides does a regular polygon have, if the measure of an exterior angle is 24 degree?

Let number of sides be n.
Sum of exterior angles of a regular polygon = 360
Number of sides = n = 360/24 = 15
Hence, the regular polygon has 15 sides.
