							$Re (z_1 \overline{z_2})=0 \Rightarrow z_1, z_2$ are perpendicular i.e. $z_1 = (\cos \theta, \sin \theta); z_2 = (-\sin \theta, \cos \theta)$ for some angle  Then $w_1 = (\cos \theta, -\sin \theta); w_2 = (\sin \theta, \cos \theta)$ Then its immediately seen that $|w_1| = 1 ,|w_2| = 1$ and w1 and w2 are also perpendicular. Which means that $Re (w_1 \overline{w_2})= 0$
