Coplanar

Pronunciation: /koʊˈpleɪ.nər/ Explain

 Click on any part of the graph that does not contain an object and drag it to rotate the view. The green shaded part represents plane a. Note that point C and line f always show in the plane. They are coplanar with plane a. Line g and point F do not always show in the plane. They are not coplanar with plane a. Manipulative 1 - Coplanar Created with GeoGebra.

Mathematical objects such as points and lines are coplanar if the lie in the same plane.[2] 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.
