Answer
Non-collinear points are points that do not lie on the same straight line. Taking the points two at a time we get the following pairs — (A, B), (B, C) and (C, A).
Through each pair of points we can draw exactly one line. So, we get three lines, namely line AB, line BC and line CA.
∴ Three different lines can be drawn through three non-collinear points A, B and C.
