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 is one in which the solution is not easy to calculate. Also, the instructor clearly explains the important skill of how to handle a math problem when the final answer cannot be simplified.
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 your class understands that the largest side may be the hypotenuse. From there, it is easy to apply the Pythagorean Theorem to solution II of the commentary.
Crossing into the realm of geometry with this video, Sal introduces the Pythagorean Theorem to viewers. He uses several examples (and right triangles) to illustrate the uses and application of the Pythagorean Theorem.
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 to examine using the theorem. Terrific activities and worksheets are embedded.
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 applets that simulate squaring the sides of a right triangle and practice putting the theorem to use. More advanced levels of the app use sides length of decimal numbers, requiring learners to deal with precision in their answer.
Do your geometry pupils complain they'll never use this stuff in real life? Prove them wrong with this straightforward instructional activity, in which they apply the Pythagorean theorem to real-world problems as well as mathematical problems. The instructional activity includes several attachments for the assignment, as well as resource links for an extension of the activity.
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 your class members a 12-inch piece of yarn with which to demonstrate a right triangle and the Pythagorean theorem triples the way that this ancient culture did.  
A quadrilateral is drawn on the coordinate plane, and eighth grade geometers find the length of each side and the diagonals by applying the Pythagorean theorem. 
Geometry juniors apply the Pythagorean theorem to two triangles to determine a final calculation. 
In this Pythagorean theorem and distance formula worksheet, young geometers use the two formulas to find the distance between points. They complete 12 problems.
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. This is a great clip to watch at home when you need a little extra homework help.
Who is Pythagoras and what is the Pythagorean Theorem? Ben knows and he's made a video all about it! The Pythagorean Theorem is defined, the procedure is demonstrated, and an example is provided. Ben also mentions how the theorem is used in architecture and engineering. Note: His narration is fast so this video might need to be slowed, stopped, and discussed.
In order to learn about the Pythagorean Theorem, young mathematicians investigate relations and patterns between different sides of a right triangle to look for possible relations among the squared sides. Once they have established the relationship, they generate visual proofs, investigate the Web for additional information about Pythagoras, and use geometry software to explore other implications of the theorem. Finally, they put the theorem to use by measuring the distance between two opposite ends of their school, both on paper and directly.
Students discover the Pythagorean Theorem.  In this discovering the Pythagorean Theorem lesson plan, students measure the lengths of various triangles to the nearest centimeter. Students record their measurements in a table.  Students square each measurement and determine the relationship the two sides of a triangle have to the hypotenuse.
Students use the pythagorean theorem to solve problems. In this geometry lesson, students solve parts of a right triangle using the properties of the pythagorean theorem.
Middle and high schoolers research the life of Pythagoras and the Pythagorean theorem. They write a short biography of Pythagoras and learn to apply the theorem in their study of right triangles.
In this geometry worksheet, 10th graders apply the Pythagorean Theorem as they determine the length of the missing leg or hypotenuse in right triangles.  The one page worksheet contains twelve questions.  Answers are included. 
In this roots and the Pythagorean Theorem worksheet, learners solve 15 different types of problems related to square roots and applying the Pythagorean Theorem. They first determine the square root of each number and then, the cube root. Pupils also determine the length of each unknown side in the illustrations shown and determine the sets of numbers that can be the lengths of the sides of a right triangle.
In this Pythagorean theorem learning exercise, 9th graders solve and complete 8 different types of problems. First, they go to the given website and copy the picture shown. Then, students draw a right triangle using the straight line between the green and blue points as its hypotenuse. They also use the Pythagorean Theorem to find the length of the hypotenuse of the right triangle.
There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own alternative representation. Links to relevant websites are also included.
