Exploring the Pythagorean Theorem

This video tutorial introduces the Pythagorean theorem, explaining how it can be used to find the length of any side of a right triangle. The theorem is presented as a squared plus b squared equals c squared, applicable only to right triangles. The video provides examples of finding the hypotenuse and other side lengths, emphasizing the importance of correctly identifying the hypotenuse as the longest side. Viewers are encouraged to practice solving problems using the theorem, with guidance on using algebra to isolate variables and solve for unknowns. The video concludes with a reminder to bring questions to class.

What is the formula for the Pythagorean theorem?

• A + B = C

• A^2 / B^2 = C^2

• A^2 * B^2 = C^2
