That shape would be a trapezoid.
parallelogram
i have a feeling its a rhombus
A shape with parallel sides but no right angles is called a parallelogram
A rhombus has all sides equal and opposite sides parallel. This includes a square which is a special case of a rhombus with all angles equal (90 degrees) as well. If opposirte sides are equal but not all sides are equal, it is a parallelogram
Without knowing their arrangement or the angles involved, all you can say is that it is a quadrilateral (4 sides). If the long sides are opposite, parallel, and equal in length -- and if the short sides are opposite, parallel, and equal in length -- you have a parallelogram. If all of the angles of the parallelogram are right angles, you have a rectangle.

a square or a parallelogram
A quadrilateral with four equal sides and parallel sides that are not perpendicular to each other is known as a rhombus. In a rhombus, opposite sides are parallel, and all four sides are of equal length. While the angles are not necessarily right angles, the opposite angles are equal, and adjacent angles are supplementary. This shape maintains its properties regardless of the angles between the sides.
The shape you are describing is a rhombus. A rhombus has two pairs of parallel sides, and all four sides are of equal length. Additionally, opposite angles are equal, and the diagonals bisect each other at right angles.
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.
