उत्तर
Given three distinct points A, B and C in a plane, they can either be collinear or non collinear.
If they are collinear, then there can be only one line joining them.
If they are non collinear, then there can be three lines joining them.
For example, if we have three distinct non collinear points P, Q and R. Then we can draw three lines l, mand n joining them.
