Answer 1

In a right-angled triangle, the longest side is hypotenuse.

Explanation:

In a right-angled triangle, the side opposite the right angle is the longest side and is called the hypotenuse.

By the Pythagorean relation the square of the hypotenuse equals the sum of the squares of the other two sides, so the hypotenuse is larger than each leg for example, in a 3-4-5 right triangle the hypotenuse 5 is the longest.
