1Introduction
The Pythagorean theorem calculator calculates the side length of a right triangle. According to the theorem a²+b²=c², given any two sides, the third side can be found. You can select the type of the two known sides (leg, hypotenuse), enter the lengths, and the tool will calculate automatically. Suitable for math learning, architectural measurement, physics calculations, and other scenarios. Simple operation with precise results.
2How to Use
Select known sides
Select the type of the two known sides, e.g., leg + leg or leg + hypotenuse.
Enter side lengths
Enter the lengths of the known sides.
Click Calculate
Click the 'Calculate' button to get the length of the third side.
3FAQ
How to input known sides?
Enter two side lengths in the input box, separated by a comma, e.g., '3,4', then select the known side type.
