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.
Its diagonals are perpendicular and intersect each other at right angles or 90 degrees with 1 pair of opposite angles equal in size and 1 pair of unequal opposite angles
It is a square
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
A quadrilateral with four right angles and opposite sides that are equal and parallel is called a rectangle.
A rhombus is a 4 equal sided quadrilateral with equal opposite acute angles and equal opposite obtuse angles with diagonals that bisect each other at right angles.
Its diagonals are perpendicular and intersect each other at right angles or 90 degrees with 1 pair of opposite angles equal in size and 1 pair of unequal opposite angles

(1) Parallelogram A parallelogram is a quadrilateral with two sets of parallel sides. The opposite or facing sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are equal.(2) SquareA square is a regular quadrilateral. This means that is has four equal sides and four equal angles.(3) RhombusA rhombus is a quadrilateral whose four sides all have the same length. Opposite angles of a rhombus have equal measure. The two diagonals of a rhombus are perpendicular.(4) RectangleA rectangle normally refers to a quadrilateral with four right angles.ParallelogramSquareRhombus

A square
A quadrilateral with four right angles and opposite sides that are equal and parallel is called a rectangle.
If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
It is no different from a quadrilateral.A quadrilateral is any shape with four sides and a rhombus has four sides, therefore it is a quadrilateral.
rectangle
