Understanding the Pythagorean Theorem on the Coordinate Plane

This video tutorial demonstrates how to use the Pythagorean theorem to find the distance between two points on a coordinate plane. It provides two examples: calculating the distance between points A and D, and between points B and E. The process involves forming right triangles where the distance between the points is the hypotenuse. The video explains the theorem's formula, applies it to find the hypotenuse, and uses a calculator to determine the approximate distance.

What is the main purpose of using the Pythagorean theorem in this tutorial?

• To find the area of a triangle

• To determine the distance between two points

• To measure the angle of a triangle

• To calculate the perimeter of a rectangle
