If z1z_1 and z2z_2 are two non-zero complex numbers such that z1z2+zˉ1zˉ2=2\frac{z_1}{z_2} + \frac{\bar{z}_1}{\bar{z}_2} = 2 and z1z2−zˉ1zˉ2=2i\frac{z_1}{z_2} - \frac{\bar{z}_1}{\bar{z}_2} = 2i (where zˉ\bar{z} denotes conjugate complex of zz and i=−1i = \sqrt{-1} ), then identify the correct statements. (A) Origin z1z_1 and z2z_2 forms a right angled triangle at z2z_2 . (B) Origin z1z_1 & z2z_2 forms a right angled triangle at origin. (C) ∣z1∣=∣z2∣|z_1| = |z_2| (D) ∣z2∣=∣z1−z2∣|z_2| = |z_1 - z_2| .
