Hypotenuse of 3 and 5
Hypotenuse = √34 ≈ 5.830952
For a right triangle with legs 3 and 5, the hypotenuse c satisfies a² + b² = c²:
3² + 5² = 9 + 25 = 34, so c = √34 ≈ 5.830952 (√34).

Frequently asked questions
What is the hypotenuse of a triangle with legs 3 and 5?
It is √34 ≈ 5.830952 (or √34 in simplified radical form). Using a² + b² = c²: 3² + 5² = 34.
Is 3, 5, … a Pythagorean triple?
No. The hypotenuse √34 is not a whole number, so 3 and 5 do not form a Pythagorean triple with an integer hypotenuse.
