One of our users asked why we do not have calculator on Pythagorean theorem.
Indeed, we've already have plenty calculators about triangles but none about right triangle. Well, may be because of it's simplicity. Anyway, if someone lazy to calculate by yourself - here it is.

##### Side length of a right triangle

If selected value is "two legs", then hypotenuse is
$c=\sqrt{a^2+b^2}$
If selected value is "leg and hypotenuse, then remained leg is
$a=\sqrt{c^2-b^2}$

P.S. Wikipedia says there are 367 ways to prove Pythagorean theorem.
