Question

Every set of three points is coplanar.
True or False

Answer 1

True.

Answer 2

Three points not in a single plane, but sharing an infinite number of planes:

Answer 3

In general three points are always coplanar. But if they are also in a straight line (i.e. are collinear), then they will share infinite number of planes.

Answer 4

So if the question asked if 3 points \(always\) define a single plane. Then false.

Answer 5

The question was (I think) whether three points lie in a plane. They always do (be it one or infinite) so the answer is true.

Answer 6

I agree. True.
