Haha , I'm sorry for the confusion!

Where i come frome we say catet (or katet) to describe the two sides that aren't the hypotenuse in a right triangle.

It comes from greek kathetos meaning the same thing.

"cos" (short for cosine) is the ratio between the adjecent catet and the hypotenuse in a right triangle. 

$${\frac{{\mathtt{catet}}}{{\mathtt{hypotenuse}}}}$$

Squaddy......I don't believe I've ever encountered the word "catet" before.....Do you know its origin  ???...We usually say adjacent "side" in the US...
