Steps of Construction :
(i) Draw a circle with the help of bangle.
(ii) Draw two chords AB and AC. Perpendi-cular bisectors of AB and AC intersect each other at O, which is the centre of the circle.
(iii) Taking a point P outside the circle, join OP.
(iv) Let M be the midpoint of OP. Taking M as centre and OM as radius draw a dotted circle which intersect the given circle at Q and R.
(v) Join PQ and PR. Thus, PQ and PR are required tangents.
