Coplanar
Non-coplanar
When a set of points could be in the same plane.
When a set of points can not be in the same plane.
Any three points will always be coplanar.
It takes at least four points to be non-coplanar.

Parallel Lines
Perpendicular Lines
- Lines in the same
plane that do not intersect.
Skew Lines
- Lines in different
planes that do not intersect and are not
parallel.
