Exercise 14.3

Ex 14.3 Class 6 Maths Question 1.
Draw any line segment (overline { PQ }) . Without measuring (overline { PQ }), construct a copy of (overline { PQ }).
Solution:
Step I: Draw (overline { PQ }) of unknown length.
Step II : Draw a line l and mark a point A on it.
Step III: Open the compass equal to PQ.
Step IV : Place the needle of the compass at A and mark a point B on l.
Thus, (overline { AB }) is a copy of (overline { PQ }).

Ex 14.3 Class 6 Maths Question 2.
Given some line segment (overline { AB }) whose length you do not know, construct (overline { PQ }) such that the length of (overline { PQ }) is twice that of (overline { AB }).
Solution:
Step I : Draw (overline { AB }) of any suitable length.
Step II : Place the needle of the compass at A and the other pencil end at B.
Step III : Draw a line l and take a point P on it.
Step IV: With the same opening of the compass, place the needle at P and mark another point Q on l.
Thus (overline { PQ }) is the required line segment whose length is twice the length of (overline { AB }) i.e (overline { PQ }) = (overline { 2AB }) .
