Frequently asked questions

What is the hypotenuse of a triangle with legs 7 and 9?

It is √130 ≈ 11.401754 (or √130 in simplified radical form). Using a² + b² = c²: 7² + 9² = 130.

Is 7, 9, … a Pythagorean triple?

No. The hypotenuse √130 is not a whole number, so 7 and 9 do not form a Pythagorean triple with an integer hypotenuse.
