Steps of construction:
1. Draw a circle with bangle.
2. Take two non-parallel chords AB and CD of the circle.
3. Draw perpendicular bisector of these chord intersecting each other at O which is the centre of the circle.
4. Take a point P outside of the circle.
5. Join OP and mark the mid point M of OP.
6. With M as a centre and radius MP draw arc on the circle at the point Q and R
7. Join PQ and PR
