This video tutorial covers the Pythagorean theorem, explaining its application in finding unknown side lengths in right triangles. It begins with an introduction to right triangles, defining the legs and hypotenuse. The video then demonstrates how to use the Pythagorean theorem to calculate the hypotenuse and missing legs through various examples, emphasizing the importance of identifying the longest side as the hypotenuse. The tutorial concludes with a special mention of the 3-4-5 triangle, a common right triangle configuration.
