What is the length of the hypotenuse of a right triangle with legs of 5 and 12 units?

What is the "hypotenuse" and "legs" of a triangle? Thanks!

The two legs form the right angle and the hypotenuse is the longest side, being opposite the right angle.

In any right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse.

x^2 + y^2 = z^2

You have the two sides of 5 and 12 from which, the hypotenuse is equal to the square root of (5^2 + 12^2) = 13.
