Any polygon, other than a triangle, can have a pair (or more) of parallel lines.
Nope it has to be a shape to have parallel sides and even then some don't
A capital "H."
A regular hexagon has three sets (pairs) of parallel line segments that form it.
A circle.
You cannot have one parallel line. There must be another line that it is parallel to. Also, 1 symmetry is meaningless - you can have one axis of symmetry or rotational symmetry of order one. The answer will depend on which one it is.
If you mean one pair of parallel lines, then you're talking about a trapezoid.
A trapezoid has 1 set of parallel lines
It might - just might - help if the "shape below" actually appeared below!
There is no shape with one parallel lines in them.If there was a shape with a parallel line in it that would just be stupid.
Well the perimeter is the straight line across the middle of the shape I would describe is a single parallel line to be my opinion
A square and a rectangle have perpendicular and parallel lines. The two side lines extending upwards from the base line are perpendicular to the base line. The line extending from each of the side lines across the top is perpendicular to the side lines. The top line is also parallel to the base line, and the side lines are also parallel to each other.
Yes. Think of a kite shape. Symmetry along its length but no parallel sides.
