Summary
With the help of this activity, we have learnt that:
When A lies outside the circle then we can draw 2 tangents passing through A.
If A lies inside the circle then there will be no tangent passing through A.
When point B is present on the circumference of the circle then there will be only one tangent passing through it. (Practically it is difficult to place point A on the circumference of the circle therefore we have taken one more point B to explain this condition
