Hypotenuse of 1 and 9
Hypotenuse = √82 ≈ 9.055385
For a right triangle with legs 1 and 9, the hypotenuse c satisfies a² + b² = c²:
1² + 9² = 1 + 81 = 82, so c = √82 ≈ 9.055385 (√82).

Frequently asked questions
What is the hypotenuse of a triangle with legs 1 and 9?
It is √82 ≈ 9.055385 (or √82 in simplified radical form). Using a² + b² = c²: 1² + 9² = 82.
Is 1, 9, … a Pythagorean triple?
No. The hypotenuse √82 is not a whole number, so 1 and 9 do not form a Pythagorean triple with an integer hypotenuse.
