Prove that in two concentric circles, the chord of the larger circle which touches the 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, a chord of length 8cm of the larger circle touches the smaller circle. If the radius of the larger circle is 5cm then find the radius of the smaller circle.

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