Question

in two concentric circles,prove that all chords of the outer circle,which touch the inner circleare equal in length.

Answer 1

Answer:

Step-by-step explanation:

Given: Two consecutive circles with centre O. AB,CD and EF are the chords of the outer circle.

To prove: AB = CD = EF.

Proof:

OP, OQ and OR are the distances of the chord AB,CD and EF from the centre.

But OP = OR = OQ = radius

Since the chords are at equal distances from the centre they are equal.
