Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
Any two lines that cross at a point. For this to be possible, they have to share a plane, can't be the same line, and can't be parallel (run side-by-side)

Parallel lines in the Euclidean plane do not intersect but all parallel lines in the projective plane intersect at the point at infinity.

If the 2 lines lie in the same plane, and they are not parallel, then they will intersect at some point. If the 2 lines are skew lines, then they are not in the same plane, and they will not intersect (but they are Not Parallel)
Two parallel lines, a plane and a line in a plane parallel to it.
