It can, but it need not have parallel lines.
A dodecahedron need not have any parallel lines.
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.
they need to look parallel
Parallel lines would always lie in the same plane. They would need to be skew lines.
Non-intersecting lines in 3-D space may be parallel but need not be.
no, if two lines are not parallel then the will eventually have to intersect.Alternate perspective:Yes, if two lines are non-parallel, they need not intersect in three dimensional space.
Parallel lines cannot intersect in the Euclidean plane. Intersecting lines are not parallel.
If the hexagons are regular, it has 3 quartets of parallel lines and one 6-tuple of parallel lines. If the bases are irregular hexagons, it can have six pairs of parallel lines and one 6-truple.
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.
It need not have any.
Parallel lines are lines that share the same slope (number in front of the x) In this case you need two lines that have 2x to be considered parallel to one another.
