Two coplanar lines that never intersect are called called parallel lines.
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
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.
Not necessarily. The Tropic of Cancer, and the Tropic of Capricorn, imaginary lines on the surface of the earth (an approximate sphere), are parallel but they are not coplanar. You could draw similar lnes on a proper sphere that were parallel but not coplanar.
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.
are two lines that are not parallel, coplanar, and do not intersect
parallel lines
Parallel lines.
No, not always. Skew lines are never coplanar, but parallel lines are.
Parallel lines are ALWAYS coplanar.
Parallel Lines or Skew Lines.
Two coplanar lines that never intersect are called called parallel lines.
Yes.
If they intersect or are parallel.
parallel
Two lines are coplanar iff they are parallel OR intersect.
Parallel lines in Euclidean space are always coplanar.
