If `z_1, z_2, z_3, z_4` are the affixes of four point in the Argand plane, `z` is the affix of a point such that `|z-z_1|=|z-z_2|=|z-z_3|=|z-z_4|` , then `z_1, z_2, z_3, z_4` are

If |z_(1)+z_(2)|=|z_1|+|z_2| then

If z_1,z_2, z_3 are complex numbers such that |z_1|=|z_2|=|z_3|=|1/z_1+1/z_2+1/z_3|=1 then |z_1+z_2+z_3| is equal to

If z_1, z_2 and z_3 , are the vertices of an equilateral triangle ABC such that |z_1 -i = |z_2 -i| = |z_3 -i| .then |z_1 +z_2+ z_3| equals:

If z_1, z_2, z_3 are distinct nonzero complex numbers and a ,b , c in R^+ such that a/(|z_1-z_2|)=b/(|z_2-z_3|)=c/(|z_3-z_1|) Then find the value of (a^2)/(z_1-z_2)+(b^2)/(z_2-z_3)+(c^2)/(z_3-z_1)
