Mathematics: The Pythagorean Theorem

THE PYTHAGOREAN THEOREM

In this module, you can study the formula and concept of the Pythagorean Theoremhow to use the Pythagorean Theorem to figure out the length of any side of a right triangle.

 

The video above, from examsolutions.co.uk, does a good job explaining the Pythagorean Theorem and how to use it. The narrator defines many important vocabulary terms, such as hypotenuse, right angle and right triangle.

Did you know?

The Pythagorean Theorem only works with right triangles, but you can use it in many different ways.

For example, builders use the Pythagorean Theorem when laying a house foundation to ensure it's square.

 

The Pythagorean Theorem is:  a2 + b2 = c2    

It means  (side)2 + (side)2 = (hypotenuse)2

Hypotenuse is the the longest side

 

The letters a, b and c are not important; instead you could use the letters x, y and z!
