Pythagorean Theorem and the Coordinate Plane

The video tutorial explains how to find the distance between two points on a coordinate plane using the Pythagorean theorem. It begins with plotting points and forming a right triangle, then calculating the hypotenuse. An example is provided, followed by a task for viewers to practice. The tutorial also covers finding the perimeter of a triangle by calculating the hypotenuse of three right triangles formed by the triangle's sides.

Describe the process to find the perimeter of a triangle in the coordinate plane.

What are the lengths of the sides of the three triangles used to find the perimeter?
