Skew Lines. :)
CorrectParallel lines as well as intersecting lines must be coplanar (in Euclidean geometry not quite sure about hyperbolic geometry...).Lines in space which neither are coplanar nor intersecting are called "skew"
Skew lines There is a vertical (or horizontal) and a diagonal!
You may have neglected to copy something else that goes with the question, as there are no "above lines".
No. Lines are infinite, so if they are not parallel, they have to intersect at some point on the plane.
