What is a regular polygon?

State the name of a regular polygon of

(i) 3 sides (ii) 4 sides (iii) 6 sides

Solution

Solution: A polygon is said to be a regularpolygon if

(a) The measures of its interior angels are equal, and

(b) The lengths of its sides are equal.

The name of a regular polygon having

(i) 3 sides is ‘equilateral-triangle’

(ii) 4 sides is ‘square’

(iii) 6 sides is ‘regular hexagon’
