Parallel lines are always the same distance from each other and never intersect.
Parallel lines
Lines that never intersect are parallel.
Two coplanar lines that never intersect are called called parallel lines.
If the lines are in the same plane and never intersect they are always parallel. Two line can not intersect and be parallel if they are in different planes though. Take a cube for example, if you have one Sid of it and take the edge and then go to the opposite side and make a horizontal line they will never intersect but are also not parallel.
parallel lines never intersect.
parellel lines
Perpendicular lines always intersect and make 90 degree angles. Parallel lines never intersect with each other.
Parallel lines never intersect and always remain equal distance from each other.
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
Parallel lines remain equal distance apart and never intersect with each other.
Parallel lines
Parallel lines remain equal distance apart and never intersect each other.
Parallel lines will never intersect. They will stay an equal distance apart at all points.
Lines that are equal distance from one another and never intersect
always. if two lines intersect, then exactly one plane contains the lines.
I think "parallel" is the word you're looking for?
