Description: Sal uses the Pythagorean theorem to find the height of a right triangle with a base of 9 and a hypotenuse of 14. Created by Sal Khan and Monterey Institute for Technology and Education.

And we know that if we have a right triangle, if we know two of the sides, we can always figure out a third side using the Pythagorean theorem.
