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 \(\overline{AB} \) .
