DO random tests still work in Coffeescript?

The description says Somehow, I knew the third triangle had its first side unmarked, rather than its second, I'll have to take that into account were I to do this right., but without any diagrams or specification, this doesn't provide enough information to solve it. "First side" and "second side" don't have standard meanings. It's certainly not sorted by length, because in one of your examples, a>b. So even though I guessed correctly that 'c' is always the hypotenuse, it would be a bit fairer to tell us this in advance.
