Pythagorean Theorem and Square Roots

The video tutorial explains how to calculate the distance between two points using the Pythagorean theorem. It begins with an introduction to the concept of distance and the theorem itself. The instructor plots two points on a coordinate plane and forms a right triangle, using the theorem to find the hypotenuse, which represents the distance. The process of simplifying the square root of 136 is demonstrated, and the final distance is approximated as a decimal. The video concludes with a note on why negative distances are not considered.
