If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
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.

The shape has to be a parallelogram since it has no lines of symmetry and all sides are equal and parallel
a pentagon has 5 sides total, and no parallel sides. A hexagon has 6 sides, so it has 3 parallel sides. any shape with an odd number of equal sides has 0 parallel sides, no matter how many sides it has. every shape with an even number of equal sides will have the # of sides divided by 2 (#/2) of parallel sides.
A rhombus has 4 sides of equal length, opposing parallel sides, and no right angles
