In two concentric circle, prove that a chord of larger circle which is tangent to smaller circle is bisected at the point of contact.

Prove that in two concentric circles, the chord of the larger circle, which touches the smaller circle, is bisected at the point of contact.

In two concentric circles prove that all chords of the outer circle which touch the inner circle are of equal length.

In two concentric circles, a chord of length 24cm of larger circle becomes a tangent to the smaller circle whose radius is 5cm. Find the radius of the larger circle.

Prove that all the chords of a circle through a given point within it, the least is one which is bisected at that point.

Prove that all the chords of a circle through a given point within it, the least is one which is bisected at that point.

The shows two concentric circles and AD is a chord of lenger circle. prove that AB=CD

In the adjoining figure, O is the centre of two concentric circles. The chord AB of larger circle intersects the smaller circle at C and D. (i) Find AC:BD . (ii) If AC=2cm , then find the length of BD.

If radii of two concentric circles are 4 cm and 5 cm , then length of each chord of one circle which is tangent to the other circle, is

If the radii of two concentric circles are 4 cm and 5 cm, then find the length of each chord of one circle which is tangent to the other circle.

The figure shows two concentric circles and AD is a chord of larger circle. Prove that : AB = CD.
