Any regular polygon with an even number of sides must have parallel sides.
A regular polygon with 100 sides, also known as a hectogon, does not have any parallel sides. In a regular polygon, each side is equal in length, and the angles between adjacent sides are also equal. Since the sides are not aligned in a way that creates parallelism, a regular polygon with any number of sides, including 100, has zero pairs of parallel sides.
A circle intersected by a pair of parallel lines.
A regular polygon with an even number of sides.
Infinitely many. Every regular polygon with 2n sides has n pairs of parallel sides. Then there are irregular polygons which can have parallel sides. And there are also irregular shapes which have parallel sides.
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.

5 pairs of parallel sides.
A square is a regular polygon with two sets of parallel sides. A parallelogram is an irregular polygon with one set of parallel sides. A rhombus is an irregular polygon with two sets of parallel sides. A rectangle is an irregular polygon with two sets of parallel sides. *Note - a regular polygon is a shape in which all sides are equal in length and all angles are equal in measurement.

The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.
A regular polygon with an even number of sides.
None. (As there are an odd number of sides, each side is opposite a vertex and there are no parallel sides.)
A decagon has 10 sides. Any regular polygon with four or more sides will have pairs of sides that are parallel. A decagon will have 5 pairs of parallel sides.
