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.
the parallel lines never intercept so they do not have any common points.
If the two lines are actually "on top of each other", they can have infinitely many points in common. If they are parallel, they have no points in common. If they are perpendicular, they have one point in common.
If there are no common points but both lines lie n the same plane they are considered "coplanar points"
Parallel lines or skew lines
The lines are PARALLEL.
Not if they are straight lines.
There are 20 common points.
intersecting lines
No, parallel lines never intersect, so they do not have any points in common. Intersecting lines have one common point.
paralell if they have no common points.
Parallel.
No. Skew lines must be in different planes. Skew lines have no common points (they never cross).
