If P is a point, then how many tangents to a circle can be drawn from the point P, if it lies On the circle.
Which of the following stateements is not true ?
(a) If a point P lies inside a circle, no tangent can be drawn to the circle, passing through P.
(b) If a point P lies on the circle, then one and only tangent can eb drawn to the circle at P.
(c) If a point P lies outside the circle, then only two tangents can be drawn to the circle from P
(d) A circle can have more than two parallel tangents, parallel to a given line.
