I recently was confronted by this monstrosity of a question in one of my mock exams.(adsbygoogle = window.adsbygoogle || []).push({});

|Z1 + Z2| ≤ |Z1| + |Z2|

I made a few attempts at it before becoming demoralized with the lack of progress..

|Z^2| was equal to Z1(conjugate)Z1

Hence equaling X^2 + Y^2

However even when expanding into x+iy form etc no avail, help is appreciated.
