Hypotenuse of 5 and 10
Hypotenuse = √125 ≈ 11.18034
For a right triangle with legs 5 and 10, the hypotenuse c satisfies a² + b² = c²:
5² + 10² = 25 + 100 = 125, so c = √125 ≈ 11.18034 (5√5).

Frequently asked questions
What is the hypotenuse of a triangle with legs 5 and 10?
It is √125 ≈ 11.18034 (or 5√5 in simplified radical form). Using a² + b² = c²: 5² + 10² = 125.
Is 5, 10, … a Pythagorean triple?
No. The hypotenuse √125 is not a whole number, so 5 and 10 do not form a Pythagorean triple with an integer hypotenuse.
