Frequently asked questions

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

It is √128 ≈ 11.313708 (or 8√2 in simplified radical form). Using a² + b² = c²: 8² + 8² = 128.

Is 8, 8, … a Pythagorean triple?

No. The hypotenuse √128 is not a whole number, so 8 and 8 do not form a Pythagorean triple with an integer hypotenuse.
