Question

if a line intersects two concentric circles (circle with the same centre) with centre 0 at A, B, C and D prove that AB =CD

Answer 1

Step-by-step explanation:

If a line intersects two concentric circles (circles with the same centre) with centre O at A, B, C and D, prove that AB = CD (see Fig.) ... Proof: ∵ The perpendicular drawn from the centre of a circle to a chord bisects the chord.
