neither, a regular hexagon's sides hit at a 120 degree angle so they are neither parallel nor perpendicular. An irregular hexagon's can, but usually don't. In a regular hexagon (all 6 sides congruent), opposite sides are parallel.
A hexagon.
There need not be any.
There are no perpendicular lines in a regular 6 sided hexagon.
A concave hexagon can have 6 perpendicular sides if you count the external angle of one. The angles would be 90, 90, 90, 90, 90, 270

A hexagon has parallel lines.

My Guess is a hexagon

No, it does have 3 sets of parallel sides though.
Yes, they can exist.
