Which of the ff. statements are true?
a. Any two points is collinear
b. If three points are collinear, then they are coplanar.
c. If three points are coplanar, then they are collinear.
My guess, and atleast my "answers":
a. False. It is true if there is a line containing both points.
b. Not always true. Point/s may be outside the same plane.
c. False. They may not be on the same line.
An advance thank you.

a) True: for any two points, there is exactly one line going through them, so then those points are collinear.
b) True: imagine a ruler, with three points on it. Those are collinear points. Now, if you set the ruler on the ground, those points are coplanar, with all of the other points on the floor. Any way you hold that ruler, all three points can be considered coplanar. You can always find another plane that has one point, but not the others, but that doesn't make the statement false, because you are forced to consider ALL three points.
c) el perfecto on this one.
