What does it mean for a polygon to be regular?

A polygon that is equiangular and equilateral is called a regular polygon.

Answer: For a polygon to be regular, all the sides must be of equal length and all the angles should be of equal measure.

A regular polygon has all angles of the same measure and all sides of the same length.

Explanation:

For a polygon to be regular, all the sides must be of equal length.

Now, if all the sides are of equal length, we also want all the interior angles to be of equal measure.

Hence, it can now be called a regular polygon.

Thus, for a polygon to be regular, all the sides must be of equal length.
