Dear Tadiparthi

Inverse Points

Now suppose we have a circle centre O and radius a. We say that points P, Q are inverse points with respect to the circle if they lie on the same radius and if .

Pole and Polar

Let P and Q be inverse points with respect to a given circle. We draw through Q a line p perpendicular to line PQ. Then p is called the polar of the point P. The point P is called the pole of the line p

If P lies outside the circle, the polar p of P is the line joining the two points of contact T, T' of the tangents from P to the circle.
