Pythagorean Theorem Calculator — Solve for a missing side of a right triangle. Enter Leg a, Leg b, Hypotenuse c (leave blank to solve for it) to get an instant, accurate result.

공식

a² + b² = c². Given the two legs, hypotenuse = √(a²+b²). Given the hypotenuse and one leg, the other leg = √(c²−a²).

단계별 안내

Enter the Hypotenuse c (leave blank to solve for it).
Click Calculate to see your result instantly.

실제 예시

Example: With Leg a = 3, Leg b = 4, the Pythagorean Theorem Calculator gives Hypotenuse: 5.

자주 묻는 질문

Does this only work for right triangles?

Yes, the Pythagorean theorem specifically applies to right triangles.

What if the hypotenuse I enter is shorter than a leg?

That's not geometrically possible — the calculation will not return a valid real result.

What inputs does the Pythagorean Theorem Calculator need?

You'll need to provide: Leg a, Leg b, Hypotenuse c (leave blank to solve for it). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Pythagorean Theorem Calculator?

The Pythagorean Theorem Calculator applies the formula exactly as calculated — a² + b² = c². Given the two legs, hypotenuse = √(a²+b²). Given the hypotenuse and one leg, the other leg = √(c²−a²). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Pythagorean Theorem Calculator free to use?

Yes, the Pythagorean Theorem Calculator is completely free, requires no signup, and runs instantly in your browser.
