Pythagorean Theorem Algebra Proof What is the Pythagorean Theorem? Pythagoras theorem was introduced by the Greek Mathematician Pythagoras of Samos. Given any right triangle with legs a a a and bb b and hypotenuse c cc like the above, use four of them to make a square with sides a+b a+ba+b as shown below: This forms a square in the center with side length c c c and thus an area of c2. Instead of a square, it uses a trapezoid, which can be constructed from the square in the second of the above proofs by bisecting along a diagonal of the inner square, to give the trapezoid as shown in the diagram. For the formal proof, we require four elementary lemmata: Next, each top square is related to a triangle congruent with another triangle related in turn to one of two rectangles making up the lower square. Forgot password? This results in a larger square with side a+ba + ba+b and area (a+b)2(a + b)^2(a+b)2.

Over 2000 years ago there was an amazing discovery about triangles: When a triangle has a right angle (90°) ... Another, Amazingly Simple, Proof. Given: A right-angled triangle ABC in which B = ∠90º. The Pythagorean Theorem says that, in a right triangle, the square of a (which is a×a, and is written a 2) plus the square of b (b 2) is equal to the square of c (c 2): a 2 + b 2 = c 2. If two triangles have two sides of the one equal to two sides of the other, each to each, and the angles included by those sides equal, then the triangles are congruent (side-angle-side). Ask the class How can we use Pythagoras’ Theorem to work out a side length other than the hypotenuse? Putting the two rectangles together to reform the square on the hypotenuse, its area is the same as the sum of the areas of the other two squares. Since ABABAB is equal to FBFBFB and BDBDBD is equal to BCBCBC, triangle ABDABDABD must be congruent to triangle FBCFBCFBC. Given: ∆ABC right angle at BTo Prove: 〖〗^2= 〖〗^2+〖〗^2Construction: Draw BD ⊥ ACProof: Since BD ⊥ ACUsing Theorem 6.7: If a perpendicular i Pythagorean Theorem Proof #7. A triangle is constructed that has half the area of the left rectangle. Theorem 6.9: In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite to the first side is a right angle. The four triangles and the square with side ccc must have the same area as the larger square: (b+a)2=c2+4ab2=c2+2ab,(b+a)^{2}=c^{2}+4{\frac {ab}{2}}=c^{2}+2ab,(b+a)2=c2+42ab​=c2+2ab. States that in a right triangle that, the square of a `(a^2)` plus the square of b `(b^2)` is equal to the square of c `(c^2)`. Thus, a2+b2=c2 a^2 + b^2 = c^2 a2+b2=c2. □AC^2 + BC^2 = AB^2. By a similar reasoning, the triangle CBDCBDCBD is also similar to triangle ABCABCABC.
