The Pythagorean Theorem

In this lesson I will teach you the Pythagorean Theorem.  I can’t overstate how important the Pythagorean Theorem is to all mathematics.  The theorem provides much of the foundation of the study of geometry and trigonometry.  Basically the Pythagorean Theorem gives us a way to find the lengths of right triangles (a triangle that has 90 degrees as one of it’s angles).  So many other theorems and formulas are based on the Pythagorean Theorem so you need to master it completely.  As you will see in the lesson the theorem uses powers and square roots so having a calculator to work problems is suggested.  Once your done with the lesson you want to practice as many different type of problems you can- the earlier you master the formula the better.  Good luck!
