Now my question;

If you know the length of the hypotenusa in a right triagle, and you know the something* of the two other sides, can you calculate what those lengths are? I think it is very possible. What if you only know the something** of the hypotenusa and the two sides?

*If AB = 4 and BC = 2, then the 'something' is 4:2, or 2:1.

**If AB = 4 and BC = 2, then the 'something' is sqrt(20):4:2, or sqrt(20):2:1.
