Pythagorean Theorem and Coordinate Geometry

This video tutorial explains how to use the Pythagorean theorem (PI tag) to calculate the distance between two points on a coordinate plane. It begins with an introduction to the theorem and its application in right triangles. The tutorial then demonstrates how to identify points on the coordinate plane and construct a right triangle. Finally, it shows the step-by-step process of calculating the distance using the PI tag formula, concluding with a summary of the method.

What is the main purpose of this video?

• To teach how to draw right triangles

• To explain the history of the Pythagorean Theorem

• To show how to calculate the distance between two points using the Pythagorean Theorem
