A rhombus
Rectangle
a rectangle does not have four equal sides and its opposite sides are equal and has four right angles
rhombus
The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.
A square has 4 equal sides, and 4 equal angles and are considered paralellagrams A rectangle has 4 equal angles but not necessarily 4 equal sides, it is also a parallelagram.. On a square all sides are congruent, while in a rectangle only opposite sides are. So when is a square not a rectangle? what defines a rectangle and a square, each shape has to have 4 right angles. the sides are parallel and that in a square all four sides are congruent while in a rectangle only the opposite sides are congruent. So a rectangle must have opposite sides that are parallel and equal and four right angles. A square must have opposite sides parallel, all sides congruent, and four right angles. a rectangle is a parallelogram with four right angles, while a square is a parallelogram with four congruent sides and four right angles. By this definition a rectangle is a square since it has opposite sides that are congruent and parallel and it has four right angles. The question is, why a rectangle is not a square? A rectangle is not a square because it is not required to have four congruent sides.
A square. Its opposite sides are equal and it has 4 right angles.

The shape you are describing is a rhombus. A rhombus has all four sides of equal length, opposite sides that are parallel, and opposite angles that are equal. When the diagonals of a rhombus are drawn, they intersect at right angles.
