Hypotenuse of 3 and 6
Hypotenuse = √45 ≈ 6.708204
For a right triangle with legs 3 and 6, the hypotenuse c satisfies a² + b² = c²:
3² + 6² = 9 + 36 = 45, so c = √45 ≈ 6.708204 (3√5).

Frequently asked questions
What is the hypotenuse of a triangle with legs 3 and 6?
It is √45 ≈ 6.708204 (or 3√5 in simplified radical form). Using a² + b² = c²: 3² + 6² = 45.
Is 3, 6, … a Pythagorean triple?
No. The hypotenuse √45 is not a whole number, so 3 and 6 do not form a Pythagorean triple with an integer hypotenuse.
