a polygon that has all angles congruent is an equiangular .....
this means that it is equiangular. All polygons are equiangular and equilateral (Equilateral means that all of the sides are congruent)
It is a regular polygon
It is an equilateral polygon. However, it is NOT a regular polygon. For that to be the case, it would also have to be equiangular: that is, all its angles must also be congruent. It is only in the case of triangles that being equilateral implies equiangularity and therefore regularity.
Equiangular
A regular polygon
No. You also need all of the sides to be congruent. For example, a rectangle has four congruent angles, but it is not a regular polygon.
It would be an irregular polygon that has not congruent sides and angles
