- lying in the same plane
- In geometry, a set of points in space is coplanar if all the points lie in the same geometric plane. For example, three distinct points are always coplanar; but a fourth point or more added in space can exist in another plane, incoplanarly.
- Having all elements, features, dimensions or functions existing in one geometric plane.
- Any searchcoil configuration in which transmit and receive windings occupy the same level or plane.
- Refers to two or more entities that lie on the same plane. Two planar surfaces, for example, that lie on the same 3-dimensional plane are considered coplanar. If these coplanar surfaces share a common edge, it is recommended that they be joined into a single surface.
