Parallel lines or skew lines
The lines are PARALLEL.
parallel
They all have parallel lines.
Parallel.
the parallel lines never intercept so they do not have any common points.
No, parallel lines never intersect, so they do not have any points in common. Intersecting lines have one common point.

Parallel lines or skew lines
The lines are PARALLEL.
Answer: Two lines that never touch or have any points in common are parallel. If there was a slight angle difference with one of the lines, they would eventually cross somewhere. Perfectly parallel lines will always remain parallel and will never cross each other. Answer: If they are also in the same plane, they are said to be parallel.

They all have parallel lines.
Parallel lines lying in a plane do not intersect each other. They share exactly zero points in common.
Intersecting lines. If they have only one point in common, then they are also non-parallel.
In a 2 dimensional plain they would have to be parallel in order to have no common point; in a 3 dimensional field they do not have to be parallel.
