Hypotenuse of 8 and 10

Hypotenuse = √164 ≈ 12.806248

For a right triangle with legs 8 and 10, the hypotenuse c satisfies a² + b² = c²:

8² + 10² = 64 + 100 = 164, so c = √164 ≈ 12.806248 (2√41).

Frequently asked questions

What is the hypotenuse of a triangle with legs 8 and 10?

It is √164 ≈ 12.806248 (or 2√41 in simplified radical form). Using a² + b² = c²: 8² + 10² = 164.

Is 8, 10, … a Pythagorean triple?

No. The hypotenuse √164 is not a whole number, so 8 and 10 do not form a Pythagorean triple with an integer hypotenuse.
