Q.4 Given $$\overline{AB}$$ of length 3.9 cm. Construct (\overline{PQ} \) such that the length of (\overline{PQ} \) is twice that of (\overline{AB} \) . Verify by measurement.

(Hint : Construct $$\overline{PX}$$ such that the length of $$\overline{PX}$$ = length of $$\overline{AB}$$ then cut off $$\overline{XQ}$$ such that $$\overline{XQ}$$ also has the length of $$\overline{AB}$$ .
