Exercise 42 Page 9

Where is plane RKN in the diagram?

L, M, P, and S

Practice makes perfect

The points R, K, and N are all on the left face of the cube. This means that the left face is contained within plane RKN. Therefore, the plane RKN is as if the left face of the cube was extended indefinitely in all directions.

The points that are not coplanar with R, K, and N are then any points that are not on the left face of the cube. These are L, M, P, and S.
