Root Explanation

Noncoplanar → It is formed from "non-" (meaning not) and "coplanar" (from Latin "co-" meaning together and "planus" meaning flat or level). The word describes points or lines that are not in the same flat plane.

Memory Tip

Think of 'not' ('non-') being used to describe points that are 'together' ('co-') but not on the same 'flat surface' ('planus'). This helps you remember that noncoplanar means not lying in the same flat plane.
