A point

z

is equidistant from three distinct points

z_1, z_2, z_3

in argand plane. If

z, z_1

and

z_2

are collinear, then arg

\left(\frac{z_3-z_1}{z_3-z_2}\right)

will be

\left(z_1, z_2, z_3\right.

in anti-clockwise sense)

View answer and explanation

Correct option: A

\frac{\pi}{2}

Option A (

\frac{{\pi}}{{2}}

) is correct because the argument of the complex number is

\pm \frac{{\pi}}{{2}}

, and we take the positive value.
