coplanar positive

Morphology

coplanar = planar (transparent) = co + planar

The prefix 'co-' meaning 'together' combines directly with the adjective 'planar' to yield 'sharing the same plane', a straightforward formation.

Etymology

Coplanar comes from the prefix co- meaning 'together' and the part plane meaning 'flat surface'. So coplanar describes points or lines that lie 'together' on the same flat surface.
