# Q1.    Draw $\overline{AB}$ of length 7.3 cm and find its axis of symmetry.

The axis of symmetry of the line segment $\bar{AB }$ will be the perpendicular bisector of $\bar{AB }$. So, draw the perpendicular bisector of AB.

The steps of constructions are as follows:

(i) Draw a line segment $\bar{AB }$ = 7.3 cm

(ii) Taking A and B as centres and radius more than half of AB, draw two arcs which intersect each other at C and D.

(iii) Join CD. Then CD is the axis of symmetry of the line segment AB.
