Re-Calling Pythagoras' Theorem. The Pythagoras’ Theorem states that: This means that the area of the square on the hypotenuse of a right-angled triangle is equal to the sum of areas of the squares on the other two sides of the triangle. The converse may or may not be true but certainty needs a separate proof. The Pythagorean Theorem and its many proofs . A simple equation, Pythagorean Theorem states that the square of the hypotenuse (the side opposite to the right angle triangle) is equal to the sum of the other two sides.Following is how the Pythagorean equation is written: a²+b²=c². Reinforcement problems involving Pythagoras' theorem, such as those found in textbooks and/or worksheets could be assigned or written on the board. 1 The theorem of Pythagoras being very important, we will give here a new proof based only on the superposition of gures. 0000039351 00000 n As I stated earlier, this theorem was named after Pythagoras because he was the first to prove it. So the entire area of this figure is a squared plus b squared, which lucky for us, is equal to the area of this expressed in terms of c because of the exact same figure, just rearranged. 0000039285 00000 n 0000002513 00000 n Now, consider it this way, x2 = 100, because 62 is 36 and 82 is 64.

Re-Calling Pythagoras' Theorem. The Pythagoras’ Theorem states that: This means that the area of the square on the hypotenuse of a right-angled triangle is equal to the sum of areas of the squares on the other two sides of the triangle. The converse may or may not be true but certainty needs a separate proof. The Pythagorean Theorem and its many proofs . A simple equation, Pythagorean Theorem states that the square of the hypotenuse (the side opposite to the right angle triangle) is equal to the sum of the other two sides.Following is how the Pythagorean equation is written: a²+b²=c². Reinforcement problems involving Pythagoras' theorem, such as those found in textbooks and/or worksheets could be assigned or written on the board. 1 The theorem of Pythagoras being very important, we will give here a new proof based only on the superposition of gures. 0000039351 00000 n As I stated earlier, this theorem was named after Pythagoras because he was the first to prove it. So the entire area of this figure is a squared plus b squared, which lucky for us, is equal to the area of this expressed in terms of c because of the exact same figure, just rearranged. 0000039285 00000 n 0000002513 00000 n Now, consider it this way, x2 = 100, because 62 is 36 and 82 is 64.
