A figure with 4 equal sides and 4 equal angles is a square :)
a square is a plain figure which has all the sides equal but a rhombus is a plain figure which has the opposite sides equal.
an equilateral triangle has all its angle and sides equal

A square is a rectangle with 4 equal sides and 4 equal angles. A rhombus is a parallelogram with 4 equal sides.
A regular polygon
