Draw any line segment, say AB. Take any point C lying in between A and B. Measure the lengths of AB, BC and AC. Is AB = AC +CB? [Note: If A, B, C are any three points on a line, such that AC + CB = AB, then we can be sure that C lies between A and B.]

1.	Draw any line segment, say AB. Take any point C lying in between A and B. Measure the lengths of AB, BC and AC. Is AB = AC +CB? [Note: If A, B, C are any three points on a line, such that AC + CB = AB, then we can be sure that C lies between A and B.]
Answer» This statement is true that if A, B, C are any three points on a line, such that AC + CB = AB, then we can be sure that C lies between A and B. IfAC + CB = AB, then A, B, and C are said to be collinear points.
