In this proof, triangle ABC is right angle and its right side is angle C. There is involvement of the Babylonians and the Egyptians in the invention of the Pythagoras Theorem but the earliest known proof of the theorem was produced by the school of Pythagoras. A second proof by rearrangement is given by the middle animation.

This way of cutting one figure into pieces and rearranging them to get another figure is called dissection. Are there other geometrical concepts that are necessary to know in order to solve this problem?

That line divides the square on the hypotenuse into two rectangles, each having the same area as one of the two squares on the legs. You can accomplish this by using proofs, manipulatives, and computer technology.

Then another triangle is constructed that has half the area of the square on the left-most side. The triangles are shown in two arrangements, the first of which leaves two squares a2 and b2 uncovered, the second of which leaves square c2 uncovered.

The dissection consists of dropping a perpendicular from the vertex of the right angle of the triangle to the hypotenuse, thus splitting the whole triangle into two parts.

To solve a particular problem, the Pythagoras Theorem can be arranged. Write your initial response in a minimum of words. The first proof starts off as rectangle and is then divided into three triangles that individually contain a right angle. Those two parts have the same shape as the original right triangle, and have the legs of the original triangle as their hypotenuses, and the sum of their areas is that of the original triangle.

By Saturday, February 7,post your response to the appropriate Discussion Area. For the formal proof, we require four elementary lemmata: The Chinese and Indians also played a role in the invention of the Pythagoras Theorem.

Apply APA standards to citation of sources. The examples you find can come from several different fields of study and applications such as construction, city planning, highway maintenance, art, architecture, and communications, to name a few.

Regardless of what the worksheet asks the students to identify, the formula or equation of the theorem always remain the same. The first diagrammatic proof of the theorem was produced by the Chinese while the Indians discovered many triples.

Do you think we would have the technology that we have today without knowledge of mathematical problem-solving tools such as the Pythagorean Theorem? Algebraic proofs Diagram of the two algebraic proofs The theorem can be proved algebraically using four copies of a right triangle with sides a, b and c, arranged inside a square with side c as in the top half of the diagram.

A large square is formed with area c2, from four identical right triangles with sides a, b and c, fitted around a small central square. Consider commenting on the following: The construction of squares requires the immediately preceding theorems in Euclid, and depends upon the parallel postulate.

To see first proof, you can use a computer or something as straight forward as an index card cut up into right triangles. Many Pythagorean triples were known to the Babylonians while the Egyptians knew and used the 3, 4, 5 triple.

The area of a rectangle is equal to the product of two adjacent sides. Labeled in different order With a different set of letters By using vertices to name the sides The symbols used in the Pythagoras Theorem are something students will find on their calculators.

Similarly for B, A, and H. When constructing your response, consider the theories, examples, and concepts discussed in your readings this module, and refer to them to support your conclusions.

Though there are many different proofs of the Pythagoras Theorem, only three of them can be constructed by students and other people on their own. Once constructed, the bisector is allowed to intersect ED at point F.

Drop a perpendicular from A to the side opposite the hypotenuse in the square on the hypotenuse. The side opposite to the right angle or simply the hypotenuse is always the longest side of the triangle Though it is the longest side of the triangle, the size of the hypotenuse can never exceed the sum of the other two squares To understand this better, take a look at a Pythagoras Theorem worksheet.

Your textbookChapter 10, Modeling with Geometrywould be a good reference to consult for some examples illustrating the use of the Pythagorean Theorem in applied situations. The examples you find must clearly demonstrate the use of the Pythagorean Theorem as a tool.

Through Wednesday, February 11,review the postings of your peers and respond to at least two of them. Such triangles are known as Pythagorean triangles. In this module, you are going to research three examples of the implementation of geometry that would employ the use of the Pythagorean Theorem as a problem-solving tool.
