Four pairs.
In a regular octagon, there can be multiple sets of parallel lines. Specifically, each pair of opposite sides of the octagon is parallel to each other. Since an octagon has 8 sides, there are 4 pairs of parallel lines, resulting in a total of 4 distinct sets of parallel lines.
4 pairs
Their are 4 pairs of parallel sides on an octagon. In fact, for any regular polygon with an even number of sides, there will be # of sides / 2 number of pairs of parallel lines.
8
A regular octagon has 8 sides and 8 vertices. To determine the number of vertical lines that can be drawn through its vertices, we consider the symmetry of the shape. In a regular octagon, there are 2 vertical lines of symmetry that can be drawn through pairs of opposite vertices. Therefore, there are 2 vertical lines in a regular octagon.

A regular octagon has 4 pairs but it need not have any.

An octagon had four pairs of parallel lines.
A regular octagon has four pairs of parallel sides.
An octagon had four pairs of parallel lines.
An octagon need not have any parallel sides. But it can have any number from 2 to 8 lines that are parallel - in pairs, triplets or quartets.

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).
