text: The distance between two points in the plane $P$ and $Q$ corresponding to the complex numbers $z_1=(x_1,y_1)$ and $z_2=(x_2,y_2)$ is given by the modulus of the vector ${\bf \it P Q} $ which is the same as the modulus of the complex number $z_1 - z_2$, namely: $$|z_1 - z_2| = \sqrt((x_1-x_2)^2
