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.
No, non-coplanar lines are not skew. Skew lines are non-coplanar lines that do not intersect and are not parallel. Non-coplanar lines are simply lines that do not lie in the same plane. Skew lines, on the other hand, are non-coplanar and not parallel, making them a specific subset of non-coplanar lines.
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.
are two lines that are not parallel, coplanar, and do not intersect
No. If two lines intersect, then they're definitely coplanar.
Non-coplanar, by a strange coincidence!
