Frequently asked questions
What is the hypotenuse of a triangle with legs 2 and 9?
It is √85 ≈ 9.219544 (or √85 in simplified radical form). Using a² + b² = c²: 2² + 9² = 85.
Is 2, 9, … a Pythagorean triple?
No. The hypotenuse √85 is not a whole number, so 2 and 9 do not form a Pythagorean triple with an integer hypotenuse.
