उत्तर

Steps of oonstruction: 

(i) Draw a line segment AB of 9 cm. 

(ii) Draw perpendicular bisector LM of AB. LM is the required locus. 

Proof: 

(i) Take any point on LM say P. 

(ii) Join PA and PB. 

Since, Plies on the right bisector of line AB. 

Therefore, Pis equidistant from A and B. 
i.e. PA = PB 

Hence, Perpendicular bisector of AB is the locus of all points which are equidistant from A and B.
