Can you help me with this exercise of complex?

Define a function from C into C that is R-linear but not C-linear, that preserves
orientación y preservar el ángulo entre dos vectores particulares (a elegir).

You forgot to state what type of help you need. Where are you stuck? What have you done so far?

Tengo que la función de C a C que cumple ser R-lineal, pero no C-lineal, es la que dado un complejo z conduce a un z conjugado, pero no entiendo la parte de preservar orientación y ángulo.

Please post in English as this is forum has mostly English speaking helpers

I have that the function from C to C that is to be R-linear, but not C-linear, is the one that given a complex z leads to a conjugate z, but I do not understand the part of preserving orientation and angle
