A rhombus is one of them
A shape that has four straight sides and four angles is defined as a quadrilateral. If all four angles are right angles, it is a rectangle, and if all four sides are congruent, it is a square.
A rectangle is a plane figure with four straight sides and four right angles, esp. one with unequal adjacent sides. A square is a plane figure with four equal straight sides and four right angles. A rhombus is a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
straight sides A parallelogram is a square when all four sides are the same length and all four angles are right angles (90 degrees).
