Question

Mark three non-collinear points $\mathrm{A},\mathrm{B}\mathrm{and}\mathrm{C}$ in your notebook . Draw lines through these points taking two at a time and name these lines . How many such different lines can be drawn ?

Answer 1

The set of points that do not lie on the same line are called non-collinear points. We cannot draw a single straight line through these points.

It is given that the three collinear points are $\mathrm{A},\mathrm{B}\mathrm{and}\mathrm{C}$.

We know that three lines namely $\mathrm{AB},\mathrm{BC}\mathrm{and}\mathrm{AC}$ can be drawn using these points as shown in the figure,
