There are no polygons (shapes with only straight-line sides) with fewer than three sides, but if you allow shapes with curved sides there are many possibilities. Examples include semicircles, annuli (donut shaped), and crescents.

Then it wouldn't be a shape then it would only be 2 parellel lines
If the shape (a quadrilateral) has only 2 parallel sides, it is a trapezoid (UK trapezium).A shape with four sides and two sets of parallel sides is a parallelogram (rectangle, square, rhomboid, rhombus) because these figures have four sides and two sets of parallel sides.
An equilateral hexagon would work. It has more than 2 pairs of parallel sides though. There is no shape with only 2 pairs of parallel sides besides a parallelogram.
a boxs lol not
Any shape that is not a triangle may have 2 parallel sides, although regular polygons only have parallel sides when the number of sides is even. For a quadrilateral, a trapezoid(UK trapezium) has 1 set of parallel sides and a parallelogram (either a rhombus, rectangle, or square) has 2 sets of parallel sides.
