In pythagoras theorem, we have the formula:
![\begin{gathered} c^2=a^2+b^2 \\ \\ c=\sqrt[]{a^2+b^2} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/fq25ibyakg4mdru0cs2aiaolaujm2d03zu.png)
The side c is the longest side in the triangle which is called the hypotenuse.
The letter c is not always on the left side.
If you are to find side a, use the formula:
![\begin{gathered} a^2=c^2-b^2 \\ \\ a=\sqrt[]{c^2-b^2} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/sqjjc05nx0cxpbkz0jmth1jl31luf4u6x6.png)
Also, if we are to find side b, we have:
![\begin{gathered} b^2=c^2-a^2 \\ \\ b=\sqrt[]{c^2-a^2} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/p1879zgh6ptimiy4y02hpt79sj308i3j78.png)
