The rule of distance between two points

The video tutorial explains how to calculate the distance between two points on a coordinate plane using the Pythagorean theorem. It begins by introducing points A and B, and then forms a right angle triangle with an additional point C. The tutorial derives the distance formula by applying the Pythagorean theorem, explaining the calculation of the square of differences between the x and y coordinates. An example is provided to calculate the distance between two given points, A(2,3) and B(5,6), and verifies the result using the midpoint rule.
