It can have anywhere between 0 and 12 pairs of parallel sides.

I'm pretty sure it is 12 pairs of parallel lines.
Up to 12 pairs.

A trapezoid (or trapezium, outside of North America) has two parallel sides.The more common definition is a four-sided figure with exactly one pair of parallel sides. By this definition, figures with two sets of parallel sides such as a rectangle are nottrapezoids.Some mathematicians use a more general definition that allows for one or more pair of parallel sides. By this definition, a rectangle, square, or rhombus would be considered as special cases of a trapezoid.
