In 2D geometry, that is the definition of parallel lines. Two non-intersecting lines are indeed parallel.
intersecting lines are lines that block each other.
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"
