Determine if the conditional and its converse are true. If they are both true, select which biconditional correctly represents them. If either the conditional or the converse is false, select the counterexample which disproves the statement: If four points are non-coplanar, then they are non-collinear. If four points are non-collinear, then they are non-coplanar.
A. Four points are non-coplanar if and only if they are non-collinear. B. If and only if four points are non-collinear are they non-coplanar. C. Counterexample: If four points are non-coplanar, they still may be collinear. D. Counterexample: Four points may be non-collinear and yet lie in the same plane.
I believe D is the answer. I know A and B are not right cuz 4 points can be non-collinear but can still be coplanar
Thanks! :D
Dont hate me if I get it wrong ;-;
If its wrong, I wouldn't blame you .-. i forget what i just learn >.< lol
