Manipulative 1: Coplanar and non-coplanar lines and points. Created with GeoGebra.

Mathematical objects such as points and lines are coplanar if the lie in the same plane.[1] In manipulative 1, lines A and B are coplanar with each other and with point C. Point D and line E are not coplanar with A, B, and C. Objects that are not in the same plane are called non-coplanar.

The grey parallelogram in manipulative 1 represents a portion of a plane. Click on the yellow points in manipulative 1 and drag them to change the figure. The yellow point labeled 'rotate' rotates the plane.
