In a right triangle with legs 3 and 4, what is the length of the hypotenuse?

Explanation:
Pythagorean theorem tells us the hypotenuse length comes from squaring the legs and adding them: c^2 = a^2 + b^2. For legs 3 and 4, c^2 = 3^2 + 4^2 = 9 + 16 = 25, so c = sqrt(25) = 5. The hypotenuse is the longest side, which fits 5. The other numbers don’t satisfy the relation for these legs, so 5 is the correct length.
