प्रश्न
If B is the midpoint of `overline"AC"` and C is the midpoint of `overline"BD"`, where A, B, C, and D lie on a straight line, say why AB = CD?
उत्तर
Since B is the mid-point of AC,
AB = BC .....(1)
Since C is the mid-point of BD,
BC = CD ....(2)
From equations (1) and (2), we may find that
AB = CD

Why is it better to use a divider than a ruler, while measuring the length of a line segment?
Draw any line segment, say `overline"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, and 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.]
