What's so special about the Triangle Inequality?(adsbygoogle = window.adsbygoogle || []).push({});

[tex] abs(x + y) <= abs(x) + abs(y) [/tex]

I have learnt it in two or three units, but it seems too obvious to be given a special name.

What have I missed?

EDIT: I screwed up the tex here... if someone can fix it that would be cool
