What is the Pythagoras Theorem Calculator?

The Pythagoras Theorem Calculator helps you find the missing side of a right-angled triangle by using the relationship between the two shorter sides and the hypotenuse. You can enter any two values—Side A, Side B, or the Hypotenuse—and the calculator automatically computes the unknown side using the Pythagorean formula. After entering your numbers, the tool quickly displays the exact missing value, making it useful for students, teachers, and anyone working with geometry, construction, or distance measurements. This calculator ensures accuracy, saves time, and simplifies mathematical problem-solving.

How to Use:

1. Enter Side A: Leave it blank if you don’t know it.
2. Enter Side B: Leave it blank if you don’t know it.
3. Enter Hypotenuse: Leave it blank if you don’t know it.
4. Click “Calculate”: The calculator determines the missing side based on the given values.
5. Review the Result: Use the answer for geometry homework, right-triangle problems, or practical measurements.
