Learning Unit: The Pythagorean Theorem

What special relationship exists among the sides of a right triangle? Explore this relationship using a computer applet, cut-and-paste activity, and video tutorial to develop the Pythagorean Theorem and its significance to right triangles.

Participants who use this resource will apply the Pythagorean Theorem to show whether or not the shaded triangle inscribed in a rectangle is a right triangle. Once all of the sides on the shaded triangle are found, it is important that...

Use the given tasks and detailed teacher's commentary to introduce your 8th graders to the Pythagorean theorem and its converse. Embedded links to information about Egyptian geometry make your presentation interesting. Consider giving...

Math scholars investigate the Pythagorean Theorem. They explore the proof of the Pythagorean Theorem by using area and by dissection. They apply what they have learned about the Pythagorean Theorem. TI-nspire handheld and appropriate...

As the second in a series on the Pythagorean Theorem, this lecture delves into some more difficult problems. Primarily, it examines the process for finding the value of a hypotenuse. It is particularly helpful because the example problem...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

As an introduction to the lesson, learners verify the Pythagorean theorem with a hands-on proof. Then, pupils use the theorem to determine whether three side lengths could form a right triangle and choose one of two real-life situations...

Pairs use the Pythagorean Theorem to work a problem dealing with utility poles. They collaborate to determine where to attach a guide wire to a pole. 

Do your geometry pupils complain they'll never use this stuff in real life? Prove them wrong with this straightforward lesson, in which they apply the Pythagorean theorem to real-world problems as well as mathematical problems. The...

Students describe, in writing and drawings, a working definition of the Pythagorean Theorem, various proofs of the Theorem and examples of its application in this technology-based lesson for the Geometry classroom. Emphasis is placed...
