What is the disadvantage in comparing line segments by mere observation? Ans: One of the main disadvantage in comparing the line segments by mere observation is that there will be high chances of miscalculation. 2. Why is it better to use a divider than a ruler, while measuring the length of a line segment? Ans: We know that rulers are very thick. Hence, when we will measure the length, then we can misread the readings due to the thickness. Therefore, it is better to use a divider than a ruler. 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+BC��=��+�� ? Ans: When we will draw any line segment AB=7cm��=7�� where C� is a point lying between A� and B� as shown in the figure below – We have AC=3cm��=3�� and BC=4cm��=4��. Therefore, AB=AC+BC��=��+�� ⇒AB=3+4⇒��=3+4 ⇒AB=7cm⇒��=7��. Yes, AB=AC+BC��=��+��. 4. If A, B, C�, �, C are three points on a line such that AB=5cm��=5�� , BC=3cm��=3�� and AC=8cm��=8�� , which one of them lies between the other two? Ans: As, the sum of AB�� and BC�� is equal to the length of the line segment AC�� . i.e., AC=AB+BC��=��+�� ⇒8=5+3⇒8=5+3. Therefore, the point B� lies in between the line segment AC�� . 5. Verify whether D� is the mid-point of AG¯¯¯¯¯¯¯¯��¯ . Ans: From the figure we can observe that AD=3cm��=3�� and DG=3cm��=3��. Therefore, D� is the mid-point. 6. If B� is the mid-point of AC�� and C� is the mid-point of BD�� , where A� , B� , C� , D� lie on a straight line, say why AB=CD��=�� ? Ans: As, given we have B� is the midpoint of AC��. ⇒AB=BC⇒��=�� Similarly, C� is the midpoint of BD��. ⇒BC=CD⇒��=�� From, the above conditions, we have ⇒AB=CD⇒��=��. Hence, proved. 7.
