Frequently asked questions
- What is the Pythagorean theorem?
- For a right triangle with legs a and b and hypotenuse c, a² + b² = c². This tool solves for c given a and b.
- Does the Pythagorean theorem work for any triangle?
- No — it only applies to right triangles, where one angle is exactly 90 degrees.
- Can I use this to find a missing leg instead of the hypotenuse?
- This tool solves for the hypotenuse from two legs. Rearranging a² + b² = c² lets you solve for a leg if you know the other leg and hypotenuse.
- Is this tool free to use?
- Yes — completely free, no account needed. Everything is calculated entirely in your browser and never uploaded to a server.
