Pythagorean Theorem Calculator
This Pythagorean Theorem calculator is a focused right-triangle tool for students who want one formula in a simple layout.
Enter two side lengths and the calculator solves the third side immediately.
It is useful for geometry, coordinate distance work, and construction-style measurements.
The result also reinforces whether the missing value is a leg or the hypotenuse.
Assumptions
- Enter exactly one missing side as 0.
- This calculator assumes a right triangle only.
- Use the general triangle calculator for non-right triangles.
How this calculator works
Formula used
The calculator uses a^2 + b^2 = c^2 and rearranges the formula depending on which side is missing.
Example calculation
If the legs are 8 and 15, the hypotenuse is 17.
