They can be but need not be.
They could be parallel lines which, between them define a plane. Or they could be non-parallel, non-intersecting lines. Imagine yourself in a cuboid room with your back to a wall. Consider the line (A) formed by the wall behind you and the wall to your right. Consider the line (B) formed by the floor and the wall opposite you. The lines A and B have no point in common butthey are not coplanar.
Points on the same plane are coplanar lines.
Non-coplanar lines refer to points operating or showing in different planes. None of the points are in the same plane.
they lie in the same plane
the same line
Two lines that do not intersect on the same plane are Parallel lines.
The lines are PARALLEL.
If there are no common points but both lines lie n the same plane they are considered "coplanar points"
paralell if they have no common points.
Parallel.
Points and lines on the same plane are coplanar.
If the question is .. " Points and lines in the same plane "? then the anwser is COPLANER
parallel
Points or lines that lie on the same plane are coplanar.
No. Skew lines must be in different planes. Skew lines have no common points (they never cross).
Points on the same plane are coplanar lines.
If they are in the same plane, then they share a common plane. Did you mean to say common point. If that's the case where they are in the same plane, but do not share a common point, then they are parallel lines.
They are lines or points that lie on the same plane. Remember 3 or more points are collinear if they lie on the same line. IF those lines lie on the same plane they are coplanar.
