Q.1 Draw any line segment \(\overline{PQ} \) . Without measuring \(\overline{PQ} \) , construct a copy of \(\overline{PQ} \) .
Answer :

I : Draw \(\overline{PQ} \) of unknown length.
II : Draw a line l and mark a point A on it.
III: Open the compass equal to PQ.
IV : Place the needle of the compass at A and mark a point B on l.
Thus, \(\overline{AB} \) is a copy of \(\overline{PQ} \).
