Frequently asked questions

What is the hypotenuse of a triangle with legs 12 and 12?

It is √288 ≈ 16.970563 (or 12√2 in simplified radical form). Using a² + b² = c²: 12² + 12² = 288.

Is 12, 12, … a Pythagorean triple?

No. The hypotenuse √288 is not a whole number, so 12 and 12 do not form a Pythagorean triple with an integer hypotenuse.
