Question

The complex numbers z1, z2 and z3 satisfying  are the vertices of a triangle which is

Solution

Correct option is

Obtuse-angled isosceles

Taking mode of both sides of given relation,

             

Hence ∆ is isosceles.  

       

  Anticlocklwise rotation implies that ∠ABC = 60o

Hence isosceles ∆
