In Figure, B D C is a tangent to the given circle at point D such that B D=30 c m and C D=7c m . The other tangents B E and C F are drawn respectively from B and C to the circle and meet when produced at A making B A C a right angle triangle. Calculate (i) A F (ii) radius of the circle.

In Fig. 10.61, B D C is a tangent to the given circle at point D such that B D=30 c m and C D=7c m . The other tangents B E and C F are drawn respectively from B and C to the circle and meet when produced at A making B A C a right angle triangle. Calculate (i) A F (ii) radius of the circle.

Draw tangent to a given circle with Centre O from a point 'R' outside the circle. How many tangents can be drawn to the circle from the point ?

Draw a tangent to a given circle with center O from a point 'R' outside the circle. How many tangents can be drawn to the circle from that point ?

Two chords AC and BD of a circle intersect each other at the point O. If two tangents drawn at the points A and B intersect each other at the point P and two tangents drawn at the points C and D intersect at the point Q, prove that angle P+ angle Q =2 angle BOC. [GP-X]

Tangents AB and AC are drawn to a circle from a point A, such that angle BAC = 40^circ . A chord CP is drawn parallel to BA. The measure of angle CBP is:

Draw a tangent to a given circle with center O from a point 'R' outside the circle. How many tangents can be drawn to the circle from that point? The distance of two points to the point of contact is the same.
