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.

If a line intersects two concenteric circles (circles with the same centre) with center O at A,B,C and D, prove that AB=CD (see figure).

In Figure,l is a line intersecting the two concentric circles,whose common centre is O, at the points A,B,C and D. Show that AB=CD

In Figure,l is a line intersecting the two concentric circles,whose common centre is O, at the points A,B,C and D. Show that AB=CD

In Figure, l is a line intersecting the two concentric circles, whose common centre is O , at the points A ,\ B ,\ C\ a n d\ D . Show that A B=C Ddot

Two cocentric circle common centre O. A line 'l' intersects these circle A,B,C and D. Prove that AB = CD.

In Figure, l is a line intersecting the two concentric circles, whose common centre is O , at the points A ,B ,C and D . Show that A B=C Ddot

A straight line intersects one of the two concentric circles at the points A and B and other at the points C and D. Prove that AC = BD.

Two circle with centres A and B intersect at C and Ddot Prove that /_A C B=/_A D Bdot

Two circle with centres A and B intersect at C and D. Prove that /_ACB=/_ADB
