Hypotenuse of 1 and 5

Hypotenuse = √26 ≈ 5.09902

For a right triangle with legs 1 and 5, the hypotenuse c satisfies a² + b² = c²:

1² + 5² = 1 + 25 = 26, so c = √26 ≈ 5.09902 (√26).

Frequently asked questions

What is the hypotenuse of a triangle with legs 1 and 5?

It is √26 ≈ 5.09902 (or √26 in simplified radical form). Using a² + b² = c²: 1² + 5² = 26.

Is 1, 5, … a Pythagorean triple?

No. The hypotenuse √26 is not a whole number, so 1 and 5 do not form a Pythagorean triple with an integer hypotenuse.
