Exercise 32 Page 385

Which plane does $C,$ $G,$ and $F$ define?

Example Solution: $B$

Practice makes perfect

Before we are able to name a point that is coplanar with $C,$ $G,$ and $F,$ we first have to find the plane that contains these three points. Points $C,$ $G,$ and $F$ are all on the back face of the cube. Extending the back face outwards in all directions will create the plane that contains them.

Points

B

and

I

are also on back face of the cube and are coplanar with

C,

F,

and

G .

This means that there are five possible solutions.

B, C, F, G, I
