We can see a point A. Five different lines are drawn from this point A. AB, AC, AD, AE and AF are the five lines. We can draw an infinite number of lines from a single point A.
Question/s to think about. 1. Move the points A, B, C, D, E and F and think how many infinite lines are possible from a single point A? 2. When two different points A and B are given then how many lines are possible which pass through these two points? 3. Think how the condition in question 1 is different from the condition in question 2?
