A concave is not a shape. It is a characteristic of one. It is like asking how many parallel lines a small has.
At least 4 lines, but no matter how many lines, every line has to be parallel with at least one other line.
one
2 parallel lines * * * * * The above answer is not wholly correct. A hexagon can have one, two or three pairs of parallel lines: a regular hexagon has 3 pairs.

A parallelogram always has one set of parallel lines, plus another set also.A trapezoid (trapezium) always has exactly one set of parallel lines and no more.Any shape with more than four sides can have one set of parallel lines, but doesn'tnecessarily have to.
All i know is a Trapezium parallelograms
A trapezoid has one set of parallel lines.
A trapezium, or any one of irregular polygons of 5 or more sides.

NO!!!! Parallelogram : Two pairs of parallel lines ; The each pair of parallel lines is the same length. Trapezium ; One pair of parallel lines, that are not the same length. The other two sides can be the same length , but not parallel. Both figures/shapes are quadrilaterals.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.

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.
Two parallel lines, so one pair of parallel lines. Which are the two horizontal lines in F. Parallel lines just have the same slope, so they will never touch. So l l are parallel lines.
parallel lines are any lines that will never touch. on a 3D plane, there will be many lines that won't intersect another. but parallel lines have a specific definition that there is no way to subcatigorize it
