A regular hexagon has 6 parallel sides (3 pairs)
An octagon can have 0, 2, 3, 4, 5, 6, 7 or 8 parallel sides. A regular octagon has 4 pairs of 2 parallel sides, (8 parallel sides in all).
Three pairs: all six sides are members of a parallel pair.

A regular hexagon has three sets (pairs) of parallel line segments that form it.
