The pythagorean theorem is actually a specific case of the Cosine Law:  
a^2 = b^2 + c^2 - 2bccosA.
Surveyors use it all the time...

say 2 guys are running at you in spiky armor, 90 degrees to each other, but stop at different distances. You use this time to calculate the distance between them, so you know how long of a line you should use to tie them both where they stand.
