Pythagorean Theorem and Right Triangles

The video tutorial introduces the Pythagorean theorem, explaining its components: the legs and the hypotenuse of a right triangle. A practical problem involving a ladder and a slide is presented, where the length of the slide needs to be determined. The instructor guides through solving the problem using the Pythagorean theorem, calculating unknown lengths, and ultimately finding the slide's length. The lesson concludes with a summary of the theorem's application.
