There may be chance of error due to improper viewing.
Question 2:
Why is it better to use a divider than a ruler, while measuring the length of a line segment?
It is better to use a divider than a ruler, because the thickness of the ruler may cause
difficulties in reading off her length. However divider gives up accurate measurement.
Question 3:
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.]
AB = 6.5 cm, AC = 3cm, CB = 3.5 cm
AC + CB = 3 cm + 3.5 cm
