If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
A geometric shape with only one set of parallel sides is a trapezoid.
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

That shape would be a trapezoid.
A quadrilateral with one pair of parallel sides and no equal sides is called a trapezoid (or trapezium in some regions). In this shape, the parallel sides are referred to as the bases, while the non-parallel sides can be of different lengths. This distinguishes trapezoids from parallelograms, which have two pairs of parallel sides and equal opposite sides.
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
Parallelogram
A trapezoid (or trapezium in some regions) is a 2D shape that has one pair of parallel sides. The parallel sides are known as the bases, while the other two sides are called the legs. In an isosceles trapezoid, the legs are of equal length, adding symmetry to the shape.
a rhombusNotice that if all 4 sides are equal, then they must be parallel.

The shape has to be a parallelogram since it has no lines of symmetry and all sides are equal and parallel
