For complex number `z,|z-1|+|z+1|=2,` then `z` lies on

If arg (z-z_1)/(z_2-z_1) = 0 for three distinct complex numbers z,z_1,z_2 then the three points are

For any two complex numbers z_(1),z_(2) the values of |z_(1)+z_(2)|^(2)+|z_(1)-z_(2)|^(2) , is

If |(z-z_(1))//(z-z_(2))| = 3 , where z_(1) and z_(2) are fixed complex numbers and z is a variable complex complex number, then z lies on a

If |(z-z_1)/(z-z_2)|=1 , where z_1 and z_2 are fixed complex numbers and z is a variable complex number, then z lies on a

The number of complex numbers z such that |z-1|=|z+1|=|z-i| is

The number of complex numbers such that |z-1|=|z+1|=|z-i| is true

If Im((az+z_(1))/(bz+z_(2)))=1 (wher z,z_(1) and z_(2) are complex number abd a,b are real number). Then z lies on

If z is a complex number such that |z|>=2 then the minimum value of |z+(1)/(2)| is
