For the first one i think its A

OpenStudy (mertsj):

I agree.

OpenStudy (mertsj):

Now the second one. A plane is modelled by a flat surface. Think of a piece of paper.

OpenStudy (mertsj):

Does it contain exactly 3 points?

OpenStudy (anonymous):

NO

OpenStudy (mertsj):

Right. I think they are trying to trick you here because it takes 3 points that are not in a line to determine a point. So they were trying to sucker you in by using that 3 point deal. But you were too smart for them.

OpenStudy (anonymous):
