TS 6th Class Maths Solutions Chapter 5 Measures of Lines and Angles Exercise 5.1
Question 1.
Give any five examples of line segments observed in your classroom.
Eg: edge of black board.
Answer:
Edge of blackboard, edge of a book, edge of threshold, edge of window, height of the room, edge of table, edge of bench.
Question 2.
Why is it better to use a divider than a ruler, while comparing two line segments ?
Answer:
While finding the length of any object, the eye should be correctly positioned (i.e.) just vertically above the marks concerned. Otherwise there may be an error due to angular viewing. To avoid this problem a better way is to use a divider. In the same way, it would be better to use a divider while comparing two line segments.
Question 3.
Measure all the line segments in the figure given below and arrange them in the ascending order of their lengths.
Line segments \(\overline{\mathbf{A B}}, \overline{\mathbf{A C}}, \overline{\mathbf{A D}}, \overline{\mathbf{A E}}, \overline{\mathbf{B C}}, \overline{\mathbf{B D}}, \overline{\mathbf{B E}}, \overline{\mathbf{C D}}, \overline{\mathbf{C E}}, \overline{\mathbf{D E}}\)
Answer:
\(\overline{\mathrm{A}} \overline{\mathrm{B}}\) = 1 cm; \(\overline{\mathrm{A}} \overline{\mathrm{C}}\) = 2 cm; \(\overline{\mathrm{A}} \overline{\mathrm{D}}\) = 3 cm; \(\overline{\mathrm{A}} \overline{\mathrm{E}}\) = 4 cm
\(\overline{\mathrm{B}} \overline{\mathrm{C}}\) = 1 cm; \(\overline{\mathrm{B}} \overline{\mathrm{D}}\) = 2.0 cm; \(\overline{\mathrm{B}} \overline{\mathrm{E}}\) = 3.0 cm
\(\overline{\mathrm{C}} \overline{\mathrm{D}}\) = 1 cm; \(\overline{\mathrm{C}} \overline{\mathrm{E}}\) = 2.0 cm; \(\overline{\mathrm{D}} \overline{\mathrm{E}}\) = 1.0cm
Ascending order: \(\overline{\mathrm{AE}}, \overline{\mathrm{AD}}, \overline{\mathrm{BE}}, \overline{\mathrm{CE}}, \overline{\mathrm{BD}}, \overline{\mathrm{AC}}, \overline{\mathrm{AB}}, \overline{\mathrm{BC}}, \overline{\mathrm{CD}}, \overline{\mathrm{DE}}\)
Question 4.
Mid point of \(\overline{\mathrm{AB}}\) is located by Swetha and Reshrna like this.
Which one do you feel correct ? Measure the lengths of \(\overline{\mathbf{A C}}, \overline{\mathbf{C B}}\) and verify.
Answer:
By observation, we can say that the mid point of \(\overline{\mathrm{AB}}\) located by Reshrna is correct. (∵ AC = CB)
AC = 1 cm; CB = 2 cm (Swetha)
AC = 1.5 cm; CB = 1.5 cm (Reshrna)
Question 5.
Each of these figures given along side has many line segments. For the almirah we have shown one line segment along the longer edge. Identify and mark all such line segments in these figures.
Answer:
(i) \(\overline{\mathrm{AB}}, \overline{\mathrm{BC}}, \overline{\mathrm{CD}}, \overline{\mathrm{DA}}\) and \(\overline{\mathrm{AC}}\) are the line segments.
(ii) \(\overline{\mathrm{AB}}, \overline{\mathrm{BC}}, \overline{\mathrm{CD}}, \overline{\mathrm{DA}}, \overline{\mathrm{AE}}, \overline{\mathrm{BF}}, \overline{\mathrm{CG}}, \overline{\mathrm{EF}}\) and \(\overline{\mathrm{FG}}\) are the line segments.
(iii) \(\overline{\mathrm{AB}}, \overline{\mathrm{BC}}, \overline{\mathrm{CD}}, \overline{\mathrm{BE}}, \overline{\mathrm{AF}}, \overline{\mathrm{FE}},\) and \(\overline{\mathrm{ED}}\) are the line segments.
