This just means that opposite sides in a shape (sides that 'look' at each other) are of equal lengths.
A regular square or a rhombus if you mean all four sides are equal in length, a parallelogram if you mean the opposite sides are equal.
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
It is not clear what you mean by "has 4 right sides opposite sides equal". If you delete the phrase "4 right sides", the answer is a rhombus.
An equilateral shape would have equal and opposite sides.
Opposite sides are parallel; opposite sides are equal; opposite angles are equal.

The description given fits that of a square or a rhombus
A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal
The description fits a square or a rhombus. In a square, all sides are of equal length, opposite sides are parallel, and all angles are equal (90 degrees). In a rhombus, all sides are also of equal length and opposite sides are parallel, but the angles are not necessarily equal, as they can vary while remaining equal in opposite pairs.

opposite the smaller sides are equal and opposite the bigger sides are equal.
A parallelogram has opposite equal parallel sides
