Think of a plane as being a sheet of paper that goes on forever in all four directions. Coplanar means that they are on the same plane. Think of how you would draw two lines (which go on forever in two directions) on that sheet of paper so that they would never meet each other (not have a point in common)--you would draw two parallel lines.
parallel
True
It is their intersection.
coplanar
Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
Concurrent coplanar forces have their lines of action intersecting at a common point, allowing them to be resolved using the parallelogram law of forces. Non-concurrent coplanar forces have their lines of action not intersecting at a common point, requiring the use of the triangle law of forces for resolution.
a point
-- They can be parallel, with no points in common, or -- They can intersect in exactly one point.
A point or, if the lines are also collinear, the line(s).
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.
