Simplifying Square Roots and Pythagorean Theorem

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 then plots two points on a coordinate plane and forms a right triangle, using the Pythagorean theorem to find the hypotenuse, which represents the distance. The process of simplifying the square root of 136 is demonstrated, and the video concludes with a discussion on the decimal approximation of the distance and why a negative distance is not applicable.
