Question

In two concentric circles, prove that all chords of the outer circle, which touch the inner circle are of equal length (with figure)...!!

Answer 1

Solution:

Let AB and CD be two chords of the circle which touch the inner circle at M and N respectively.

To prove:

AB = CD

Explanation:

Since AB and CD are tangents

to the smaller circle .

OM = ON

/* radius of the smaller circle */

AB and CD are the two chords

of the larger circle such that

they are equidistant from the centre.

Hence ,

AB = CD
