How to find the hypotenuse of a triangle using Pythagorean Theorem

The video tutorial explains the Pythagorean theorem, focusing on solving for the hypotenuse of a triangle. It begins with labeling the sides of a triangle and proceeds to calculate the hypotenuse using given side lengths. The instructor emphasizes that the hypotenuse cannot be negative, as it represents a length in a triangle. The lesson concludes with a discussion on why only positive values are considered for side lengths in this context.
