A(a^{-}), B(b^{-}), C(c^{-}), D(d^{-}) are four concyclic points, such that xa^{-}+yb^{-}+zc^{-}+td^{-}=0^{-}, x + y + z + t = 0 where x, y, z, t are constants not all zero. If the chords AB and CD intersect at P, then

Correct Answer is : |xy||−a−−b|2=|zt||−c−−d|2

|xy|\,|a^{-}+c^{-}|^2=|zt|\,|b^{-}+d^{-}|^2

|xy|\,|a^{-}-b^{-}|^2=|zt|\,|c^{-}-d^{-}|^2

|xt|\,|a^{-}-c^{-}|^2=|yz|\,|b^{-}-c^{-}|^2

|xz|\,|b^{-}+d^{-}|^2=|yt|\,|a^{-}+c^{-}|^2
