Maths p3 - complex inequalities

[Mortal9090]

Hello all,

its difficult to ask this question, so i am pasting it from the syllabus:

illustrate simple equations and inequalities involving complex numbers
by means of loci in an Argand diagram, e.g. |z – a |< k, |z – a|= |z – b|,
arg(z – a) = α.

So far I understand the complex numbers extremely well - except this |z-a| thingie...

Can you please point out to me on some specific notes/videos specifically which explains how to check these inequalities? e.g. z could be a complex number, but what is a, and k and b above and so on..?

thanks
