Proving the Pythagorean Theorem

If you'd like your lesson on the Pythagorean Theorem to be fun and engaging, check out a math puzzle activity for high schoolers. Your learners will enjoy this visual puzzle that shows how the Pythagorean Theorem works.

Challenge scholars to prove the Pythagorean Theorem geometrically by using a cut-and-paste activity. They then must solve for the missing sides of right triangles.

No geometry class is complete without a proof. A short video in the Socratica Geometry playlist covers an algebraic proof of the Pythagorean Theorem. Simplifying an equation with two equivalent expressions for the area of a square leads...

The Pythagorean Theorem works for something other than right triangles; show your class all it can do. Using information from the Pythagorean Theorem, the video shows how to determine whether a triangle is an acute or obtuse triangle....

In this video, Sal introduces the Pythagorean Theorem to viewers, crossing into the realm of geometry. He uses several examples, including right triangles, to illustrate the applications and uses of the Pythagorean Theorem.

This lecture, the second in a series on the Pythagorean Theorem, delves into more complex problems. It primarily examines the process of finding the value of a hypotenuse. The example problem is beneficial because the solution is not...

This lecture, the second in a series on the Pythagorean Theorem, delves into more complex problems. Primarily, it examines the process of finding the value of a hypotenuse. It is beneficial because the example problem is one in which the...

Your class knows the Pythagorean Theorem, but can they prove it? A series of three videos shows two proofs of the Pythagorean Theorem and use it to classify triangles. 

Need to find the length of a side of a right triangle? Just use the Pythagorean Theorem! Follow along as the tutor defines the Theorem, explains how it works, then uses it to determine the missing length of a right triangle. 

There is more than one way to prove the Pythagorean Theorem. Euclid and Einstein found the same way to prove the Pythagorean Theorem. The video introduces several other ways to prove the theorem along with the history of its use.
