mathmate · Answer

As in the other problem ANY three of the four letters on the plane is sufficient.
THREE points are needed to define a plane.  Four points can make trouble if they are not coplannar.

So is it plane XTV?

mathmate · Answer

Are the three letters X,T,V out of the list {L,T,V,X}? 
I don't usually work with answer choices, but perhaps you may want to check the answer choices for typos.
