Hypotenuse of 5 and 9
Hypotenuse = √106 ≈ 10.29563
For a right triangle with legs 5 and 9, the hypotenuse c satisfies a² + b² = c²:
5² + 9² = 25 + 81 = 106, so c = √106 ≈ 10.29563 (√106).

Frequently asked questions
What is the hypotenuse of a triangle with legs 5 and 9?
It is √106 ≈ 10.29563 (or √106 in simplified radical form). Using a² + b² = c²: 5² + 9² = 106.
Is 5, 9, … a Pythagorean triple?
No. The hypotenuse √106 is not a whole number, so 5 and 9 do not form a Pythagorean triple with an integer hypotenuse.
