The complex numbers corresponding to the endpoints of one diagonal of a square drawn on a complex plane are 1 + 2i and -2 – i. what are the complex numbers corresponding to the endpoints of the square's other diagonal?

On the complex plane, the number is mapped onto the point with coordinates .

In other words, the x coordinate is the real part of the number, while the y coordinate is the complex part of the number.

Viceversa, if you start from a point , you can identify the number .

So, the endpoints of the diagonal are the points and . These are points A and C in the attached figure.

This means that points B and D have coordinates

So, the correspondant complex numbers are

b. x + 1
