All of the angles are equal in a "regular" polygon. (All of the sides are too.)
It is then called a regular polygon when all angles and sides are of equal values.
Only when it is a regular polygon that all interior angles are of equal measure
If a shape has equal angles and side lengths then it is known as a regular polygon
Only if the polygon is "regular".
A polygon with 6 equal sides and angles is called a hexagon.
A polygon with sides of equal length and equal angles is termed a regular polygon.
Only if the polygon is a "regular" one.
If all of its interior angles are equal then it is a regular polygon
They may, or may not, be equal. If you are talking about a regular polygon, all angles are equal in measure. If it is not a regular polygon, the angles are most likely different.
