Question

If a line intersects intersected 2003 the circles circles with the same Centre with Centre O at a b c and d prove that AB equal CD​

Answer 1

Answer:

Step-by-step explanation:

OM ⊥ AD is drawn from O.

OM bisects AD as OM ⊥ AD.

⇒ AM = MD --- (i)

also, OM bisects BC as OM ⊥ BC.

⇒ BM = MC --- (ii)

From (i) and (ii),

AM - BM = MD - MC

⇒ AB = CD
