Parallel lines
What is non-coplanar lines?
yes, two lines can be coplanar.
No, not always. Skew lines are never coplanar, but parallel lines are.
No. If two lines intersect, then they're definitely coplanar.
Parallel lines in Euclidean space are always coplanar.
Skew lines can refer to non-coplanar lines and, if that is the case, they cannot cross.
They do not cross. Lines that are parallel go in the same direction, but some distance apart. Coplanar means they are in the same horizontal plane. Therefore the two lines can never cross each other.
skew lines
What is non-coplanar lines?
coplanar lines are lines lying on the same plan.
yes, two lines can be coplanar.
Coplanar lines that do not intersect are called parallel lines.
No, not always. Skew lines are never coplanar, but parallel lines are.
Non-coplanar, by a strange coincidence!
are two lines that are not parallel, coplanar, and do not intersect
No. If two lines intersect, then they're definitely coplanar.
they are skew lines.
