Coplanar Lines. Coplanar Lines are lines which lie on the same plane. Two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. Lines in three dimensional space are coplanar, only if they are not skewed lines. Two lines which are neither parallel nor intersecting are called skewed lines.
It's a similar idea to coplanar. Just as collinear points all lie on a straight line, in the three dimensional world, when a set of points all lie on the same plane, they are called coplanar.For more see Coplanar points.bviously two points are always collinear, since a straight line can always be drawn through two points. Sometimes it is spelled 'colinear' (with one L).
