trapezoid
a square
Such a shape cannot exist.
It's a parallelogram.
A rectangle.
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.

That would be a trapezoid. A trapezoid does not have to have two right angles it only needs to have two parallel sides. There is not a name for the exact quadrilateral you are looking for but the shape is still within the definition of a trapezoid.

There are quadrilaterals that have no parallel sides. (basically, a quadrilateral is just any enclosed shape with 4 sides) But all quadrilaterals have angles.
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 shape with no right angles but is still a quadrilateral is called a rhombus. A rhombus has four sides of equal length and opposite sides that are parallel to each other. Although its angles are not right angles, they are all congruent.
