The number of pairs of parallel sides of the polygon have no parallel sides if n is odd and n/2 pair of parallel sides if n is even.
The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
A regular polygon has n sides.
Then the number of pairs of parallel sides of the polygon will be
IF n is odd, then none of the sides are parallel.
If n is even, then the number of pair of parallel sides will be n / 2.
