Distance and Triangle Properties

The video tutorial explains how to calculate the distance between two coordinate points using Pythagoras theorem. It provides examples with both positive and negative coordinates, demonstrating how to form a right-angled triangle and calculate the hypotenuse, which represents the distance. The tutorial emphasizes understanding the differences in x and y values to determine the triangle's sides and concludes with a summary of the method.
