Hypotenuse of 4 and 5
Hypotenuse = √41 ≈ 6.403124
For a right triangle with legs 4 and 5, the hypotenuse c satisfies a² + b² = c²:
4² + 5² = 16 + 25 = 41, so c = √41 ≈ 6.403124 (√41).

Frequently asked questions
What is the hypotenuse of a triangle with legs 4 and 5?
It is √41 ≈ 6.403124 (or √41 in simplified radical form). Using a² + b² = c²: 4² + 5² = 41.
Is 4, 5, … a Pythagorean triple?
No. The hypotenuse √41 is not a whole number, so 4 and 5 do not form a Pythagorean triple with an integer hypotenuse.
