**Mathematics **

**(Ex. 5.1)**

**Question 1.**What is the disadvantage in comparing line segments by mere observation?

**Answer:** 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?

**Answer: **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 {tex}\overline {{\text{AB}}} .{/tex} 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, hence we can be sure that C lies between A and B.]**Answer: **Yes.

AB = 6.5 cm, AC = 3cm, CB = 3.5 cm

AC + CB = 3 cm + 3.5 cm = 6.5 cm = AB

**Question 4.**If A, B, C are three points on a line such that AB = 5 cm, BC = 3cm and AC = 8 cm, which one of them lies between the other two?

**Answer: **{tex}\overline {{\text{AC}}} {/tex} is the longest line segment, thus B is the point between A and C.

**Question 5.**Verify whether D is the mid-point of {tex}\overline {{\text{AG}}} .{/tex}

**Answer:** AD = 3 units, DG = 3 units

AD = DG.

Thus, D is the mid-point.

**Question 6. **If B is the mid-point of {tex}\overline {{\text{AC}}} {/tex} and C is the mid-point of {tex}\overline {{\text{BD}}} ,{/tex} where A, B, C, D lie on a straight line, say why AB = CD?

**Answer:** B is the mid-point of {tex}\overline {{\text{AC}}} {/tex}.

{tex}\therefore {/tex} AB = BC ……….(i)

And C is the mid-point of {tex}\overline {{\text{BD}}} {/tex}.

{tex}\therefore {/tex} BC = CD ……….(ii)

From eq. (i) and (ii),

AB = CD
