Chaper 14 Practical Geometry (Ex. 14.3)
Question 1. Draw any line segment Without measuring construct a copy of
Answer: Steps of construction:

(i) Given whose length is not known.
(ii) Fix the compasses pointer on P and the pencil end on Q. The opening of the instrument now gives the length of .
(iii) Draw any line Choose a point A on Without changing the compasses setting, place the pointer on A.
Draw an arc that cuts at a point, say B. Now is a copy of .

Question 2. Given some line segment whose length you do not know, construct such that the length of is twice that of
Answer: Steps of construction:

(i) Given whose length is not known.
(ii) Fix the compasses pointer on A and the pencil end on B. The opening of the instrument now gives the length of .
(iii) Draw any line Choose a point P on Without changing the compasses setting, place the pointer on P.
(iv) Draw an arc that cuts at a point R.
(v) Now place the pointer on R and without changing the compasses setting, draw another arc that cuts at a point Q.
Thus is the required line segment whose length is twice that of AB.
