**Ex 14.3 Class 6 Maths Question 1. Draw any line segment PQ. Without measuring PQ, construct a copy of PQ.**

**Answer**

**Step 1:** Draw PQ of unknown length.

**Step 2:** Draw a line l and mark a point A on it.

**Step 3:** Open the compass equal to PQ.

**Step 4:** Place the needle of the compass at A and mark a point B on l.

Thus, AB** **is a copy of PQ.

**Ex 14.3 Class 6 Maths 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.**

**Answer**

**Step 1:** Draw AB of any suitable length.

**Step 2:** Place the needle of the compass at A and the other pencil end at B.

**Step 3:** Draw a line l and take a point P on it.

**Step 4:** With the same opening of the compass, place the needle at P and mark another point X on l.

**Step 5:** Now keeping compass open with same length, we keep pointed end on X and draw an arc on line l.

Thus PQ is the required line segment whose length is twice the length of AB i.e. PQ = 2AB
