Construction of Tangents to a Circle-
We already know that if a point lies inside a circle, there cannot cannot be a tangent to the circle through this point. However if a point lies on the circle, then there is only one tangent to the circle at this point and it is perpendicular to the radius through this point.
If a point lies outside the circle, there will be two tangents to the circle from this point.
