- A tangent PA is drawn fron an external point P to a circle of radius 3 cm such that the distance of the point P from O is 6cm.Find yhe value of.
- Draw two concentric circles of radio 3 cm and 5 cm . Taking a point on the outer circle , construct the pair of tangents to the inner circle.
- Two circles touch each other externally at O. Prove that the common tangent at O bisects the other two common tangent segments PQ and RS.
- Two concentric circles are given. Prove that all chords of the circle with the larger radius which touch the circle with the smaller radius are congruent.
