A regular heptagon has no parallel sides.
There is no such shape. There is a heptagon (7-sides) or an octagon (8 sides) but not hectogen!
You can have 0, 1, 2, or 3 pairs of parallel sides in a heptagon.
No, a heptagon cannot be parallel but two heptagons can.A heptagon can be concave.

None.
A heptagon s bounded by seven straight sides.
An irregular 7 sided heptagon normally has no lines of symmetry depending how it is constructed.
