Coplanar atoms are atoms that lie in the same plane.....

Explanation:

And given simple geometry, ANY THREE ATOMS in the universe are coplanar.

From VESPER we know that a molecule that an #AX_3# or #AX_2E# molecule will have a geometry based on a trigonal plane. #/_X-A-X=120^@#...in that the trigonal plane minimizes interactions between the three regions of electron density.
