Distance in the Coordinate Plane

The video tutorial explains how to find the diagonal distance on a coordinate plane using the Pythagorean theorem. It begins with an introduction to the problem involving line segment GH, which is graphed on a coordinate plane. The tutorial guides viewers through setting up the problem, using the Pythagorean theorem to calculate the length of the hypotenuse, and identifying the legs of the right triangle. The lesson concludes with a recap of the key concepts and a summary of the solution process.
