### plane

What does it mean for something to be in the same plane? I never really understood what this means and how to approach this question.

Any three points make up a plane. Think about a plane as a sheet of paper; this is how I visualize it. If three atoms are on the same plane, that means that the three atoms can be attached to each other through a "sheet of paper".

### Re: plane

Yes, this is a good example^. I also like to visualize the atomic models that Dr. Lavelle had in class when discussing shapes. Being on the same plane means that a certain number of points are flat. So, trigonal planar, for example, all 3 atoms are in the same plane. We could see that in the model because it was a "flat" triangle. However, when we have something like octahedral, there are 4 atoms on the same plane that form a "flat square" and two atoms that stick out from the square vertically. Those two are now in a different plane because they don't lay flay with the others.
