Steps of construction:
1. Draw a line segment AB = 5.4 cm.
2. Draw the perpendicular bisector \(\overleftrightarrow {XY}\) of AB.
3. Take any point P on \(\overleftrightarrow {XY}\).
4. With P as centre and PA as radius draw a circle.
5. Let Q be another point on XY.
6. Draw the circle (Q, \(\overline {QA}\)).
