Any polygon with any even number of sides CAN have 2 pairs of parallel lines. Parallelograms, rhombuses, rectangles, and squares always do.

The shape that has two pairs of parallel sides is a parallelogram. It is either a rectangle, rhomboid, square, or rhombus (all special cases of the parallelogram)

The set of parallelograms is is often confused with the set of trapezoids. Trapezoids are a little confusing in themselves because, although mathematicians world-wide define them as quads with two (and only two) parallel sides, in Britain trapezoid is sometimes used to refer to a quad with no parallel sides. ref. Merriam-Webster's Collegiate Dictionary.

Every parallelogram ... including every rhombus, rectangle, and square ...

must have two pairs of parallel lines.

Any shape with more than four sides can have 2 pairs of parallel sides,

but it doesn't necessarily have to.

A square is one example that has two pairs of opposite parallel sides.

All parallelograms have. (That includes rhombuses, rectangles, and squares.)

Any other polygon with any even number of sides can also manage that.
