I am getting it as 0.5+i√3/2.
Can you show your working so that your (or my) mistake might be clear ?
z1,z2,z3 are three complex numbers such that (z3-z1)/(z3-z2)=∂
find ∂ such that it represents an equilateral triangle
i got 0.5±i√3/2 as the answer.in fact these both were in the options too.but the final answer was given to contain only one with + sign.
did i do some error?

u got 0.5+i√3/2 by rotating one of sides by an angle of pi/3 right??
and how about rotating by -pi/3[7][7][12]

I think there is no such -pi/3 or pi/3 when you don't know the relative positions of z1 z2 and z3. Its simply the angle between the two rays which is pi/3
