Complex Numbers (1 Viewer)

Okay I'm all good with everything in complex numbers except vectors and that shit fucks me up lol. So I need help with this question:

OPQR is a square in an Argand diagram where O is the origin. The point P is given by z = rcis(theta). Find the complex numbers represented by Q and R

like what the literal fuck is that

Rotate P by 90 degrees anticlockwise so you get iz, which would be R.

Add the two complex numbers representing P and R to get Q, so (1 + i)z.

You could choose to rotate P 90 degrees clockwise first, either way is fine.

Oh is that all? Thank you like thats what I did first and got the same for Q but then I thought that I was suppose to sub in the z = rcis(theta) or something into the point which gave me a weird answer
