Question

Quizplus · Accepted Answer

The third side of a right triangle can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Therefore, if the legs are 5 cm and 12 cm, the length of the hypotenuse is the square root of (5^2 + 12^2) = sqrt(25 + 144) = sqrt(169) = 13 cm.
