Construction 11.3 : To construct the tangents to a circle from a point outside it.
Steps of Construction:
1) Draw a circle with centre O.
2) Take a point P outside circle.
3) Join PO. With the help of compass we bisect PO.
4) Let M be the midpoint of PO.
5) Taking M as centre & MO as radius, draw circle.
6) Let it intersect the given circle at Q and R.
7) Join PQ and PR.
8) PQ and PR are required 2 tangents.
