Two lines that are not coplaner exist on two different planes. These lines do not and will not intersect by simple definition. It is however, when speaking of three or more lines, when the possibility that two or more of them may intersect.
skew lines are noncoplanar lines, which means they aren't parallel and they also don't intersect skew lines do not intersect and are not coplanar
Vectors that sum to zero are coplanar and coplanar vectors sum to zero.
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
No; there is no physical way to intersect a plane and a double-napped cone to obtain parallel lines. The problem lies in getting a second line that doesn't intersect the first, since both cones intersect at a point, there is no way get a second line without intersecting the first line.
The lines are perpendicular, and intersect at the point (1.35, 3.55) .
Coplanar lines that do not intersect are called parallel lines.
are two lines that are not parallel, coplanar, and do not intersect
No. If two lines intersect, then they're definitely coplanar.
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
Coplanar lines can intersect an infinite amount of times.
Two coplanar lines that never intersect are called called parallel lines.
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
