If lines lie in two planes, then the lines are coplanar.
Parallel Lines - Skew lines are lines that do not intersect and do not lie in the same plane. If two lines lie in the same plane they they must either intersect or they are parallel.
No because only co-linear lines lie on the same plane
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.
Lines which lie on the same plane and have the same length are known as symmetry lines
Skew lines cannot lie in the same plane.
Two lines can lie in one plane. For example, parallel lines are lines that intersect and lie in the same plane.
C.intersecting lines
If lines lie in two planes, then the lines are coplanar.

Parallel
Coplanar.

coplanar (which means that they lie on the same plane)
