Hypotenuse of 4 and 7

Hypotenuse = √65 ≈ 8.062258

For a right triangle with legs 4 and 7, the hypotenuse c satisfies a² + b² = c²:

4² + 7² = 16 + 49 = 65, so c = √65 ≈ 8.062258 (√65).

Frequently asked questions

What is the hypotenuse of a triangle with legs 4 and 7?

It is √65 ≈ 8.062258 (or √65 in simplified radical form). Using a² + b² = c²: 4² + 7² = 65.

Is 4, 7, … a Pythagorean triple?

No. The hypotenuse √65 is not a whole number, so 4 and 7 do not form a Pythagorean triple with an integer hypotenuse.
