I can't stand this fucking cringe. It's fractions of a turn, not "degrees".
"Why yes, I'd like to turn 90 degress" or "Why yes, it's a quarter turn"?
"270 degrees" or "3/4"?

Radians are barely better. Mixing a constant used to talk about diameters in order to measure radius lengths... Disgusting...

I have half a mind to put out a lengthy YouTube series on all the theorems listed on Wikipedia's list of theorems, but with none of this horrific Pi and angleshit.
