Pythagoras theorem calculator

Enter the values of any 2 variables and the value of the remaining variable will be calculated.

This program uses the following formulas below to calculate the value of the missing variable:

$\begin{aligned} c^2=a^2+b^2 \\ c=\sqrt{a^2+b^2} \\ a^2=c^2-b^2 \\ a=\sqrt{c^2-b^2} \\ b^2=c^2-a^2 \\ b=\sqrt{c^2-a^2} \\ \end{aligned}$
