Exploring Right Triangles and the Pythagorean Theorem

The video tutorial explains how to find the length of an unknown side in a right triangle using the Pythagorean theorem. It begins by identifying the given side lengths and the hypotenuse. The Pythagorean theorem is then applied to set up an equation, which is solved to find the unknown side. The process includes calculating the square of the given sides, subtracting to isolate the unknown side, and taking the square root to find its length. The tutorial concludes with an estimation of the square root to understand its approximate value.

What type of triangle is being discussed in the problem?
