NCERT Solutions for Class 6 Maths Chapter 14 Practical Geometry Ex 14.3

Question 1.
Draw any line segment PQ¯¯¯¯¯¯¯¯. Without measuring PQ¯¯¯¯¯¯¯¯ . construct a copy of PQ¯¯¯¯¯¯¯¯.
Solution :
Step 1. Given PQ¯¯¯¯¯¯¯¯ whose length is not known.
Step 2. Fix the compasses pointer on P and the pencil end on Q. The opening of the instrument now
gives the length of PQ¯¯¯¯¯¯¯¯.
Step 3. Draw any line l. Choose a point A on /. Without changing the compasses setting, place the pointer on A.
Step 4. Swing an arc that cuts l at a point, say, B. Now AB¯¯¯¯¯¯¯¯ is a copy of PQ¯¯¯¯¯¯¯¯.

Question 2.
Given some line segment AB¯¯¯¯¯¯¯¯, whose length you do not know, construct PQ¯¯¯¯¯¯¯¯ such that the length of PQ¯¯¯¯¯¯¯¯ is twice that of AB¯¯¯¯¯¯¯¯.
Solution :
Step 1. Given AB¯¯¯¯¯¯¯¯ whose length is not known.
Step 2. Fix the compasses pointer on A and the pencil end on B. The opening of the instrument now gives the length of AB¯¯¯¯¯¯¯¯.
Step 3. Draw any line l. Choose a point P on l. Without changing the compasses setting, place the pointer on P.
Step 4. Strike an arc that cuts l at a point, say, X.
Step 5. Now fix the compasses pointer on X. Strike an arc away from P that cuts l at a point, say, Q. Now, the length of PQ¯¯¯¯¯¯¯¯ is twice that of AB¯¯¯¯¯¯¯¯.

Question 1

Draw a line segment of length 4 cm.

Construction Steps

1. Draw a straight line using a ruler.
2. Mark a point A.
3. Measure 4 cm from point A using the ruler.
4. Mark another point B.
5. Join points A and B.

Result

$AB=4\text{cm}$

Question 2

Draw a line segment of length 6 cm.

Steps

1. Draw a straight line.
2. Mark point P.
3. Measure 6 cm from P.
4. Mark point Q.
5. Join P and Q.

Result

$PQ=6\text{cm}$

Question 3

Draw a line segment of length 8 cm.

Steps

1. Draw a straight line using a ruler.
2. Mark point X.
3. Measure 8 cm carefully.
4. Mark point Y.
5. Join X and Y neatly.

Result

$XY=8\text{ cm}$
