Frequently asked questions
What is the hypotenuse of a triangle with legs 8 and 9?
It is √145 ≈ 12.041595 (or √145 in simplified radical form). Using a² + b² = c²: 8² + 9² = 145.
Is 8, 9, … a Pythagorean triple?
No. The hypotenuse √145 is not a whole number, so 8 and 9 do not form a Pythagorean triple with an integer hypotenuse.
