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.
A square or rectangle are the only regular polygons, but many other shapes have two right angles and two parallel lines.
No lines are parallel in a regular pentagon.
all right some body said that Ellipse Circle Oval but parallel shapes need to have lines so they are not parallel shapes so all i know that are not parallel is a diamond and a rhombus
A hexagon has three pairs of parallel sides. A pentagon has no lines parallel. Above answer is correct but only if they are regular hexagon and pentagons. A non-regular hexagon can have as little as none parallel lines. A non-regular pentagon can have two parallel lines.

Right triangles have a set of perpendicular lines and no parallel lines.

A regular pentagon has no parallel lines.

A regular octagon has four pairs of parallel lines.
A hexagon has three pairs of parallel sides. A pentagon has no lines parallel. Above answer is correct but only if they are regular hexagon and pentagons. A non-regular hexagon can have as little as none parallel lines. A non-regular pentagon can have two parallel lines.
