Hypotenuse of 2 and 8
Hypotenuse = √68 ≈ 8.246211
For a right triangle with legs 2 and 8, the hypotenuse c satisfies a² + b² = c²:
2² + 8² = 4 + 64 = 68, so c = √68 ≈ 8.246211 (2√17).

Frequently asked questions
What is the hypotenuse of a triangle with legs 2 and 8?
It is √68 ≈ 8.246211 (or 2√17 in simplified radical form). Using a² + b² = c²: 2² + 8² = 68.
Is 2, 8, … a Pythagorean triple?
No. The hypotenuse √68 is not a whole number, so 2 and 8 do not form a Pythagorean triple with an integer hypotenuse.
