The correct answer to this question is letter "B. equilateral." Complete this statement: A polygon with all sides the same length is said to be equilateral.
Equilateral means all sides are the same length, equiangular means all angles are the same degrees, and regular means both equiangular and equilateral. Convex means that the interior angles can have a maximum of 180 degrees each; no vertexes can point to the center.
