Finding Distance Between Points on the Coordinate Plane

The video tutorial introduces the concept of distance as the length between two points, using examples like a 100-meter dash and GPS navigation. It explains how to find the distance between two endpoints on a coordinate plane using the distance formula, with a detailed example involving line segment AB. The tutorial connects the distance formula to the Pythagorean theorem, illustrating its application in right triangles. Another example demonstrates finding the length of a diagonal in a quadrilateral on the coordinate plane, emphasizing the use of the distance formula and rounding results.
