A 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.
All quadrilaterals apart from rectangles. Even parallelograms have adjacent angles that are not equal.
In the U.S., that is a specific kind of "trapezium", which is a quadrilateral with no parallel sides.AnswerA quadrilateral with no parallel sides and no equal sides is basically just that, a quadrilateral.
A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
It is not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
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 rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
quadrilateral
A trapezium.
A trapezoid.
It is a rectangle.
A Quadrilateral Kite!
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
A square or maybe a rectangle as well would fit the given description
