The discovery of Pythagoras’ theorem led the Greeks to prove the existence of numbers that could not be expressed as rational numbers. For example, taking the two shorter sides of a right triangle to be 1 and 1, we are led to a hypotenuse of length , which is not a rational number. This caused the Greeks no end of trouble and led eventually ...The Pythagorean theorem is a way of relating the leg lengths of a right triangle to the length of the hypotenuse, which is the side opposite the right angle. Even though it is written in these terms, it can be used to find any of the side as long as you know the lengths of the other two sides.Use the Pythagorean Theorem. The Pythagorean Theorem is a special property of right triangles that has been used since ancient times. It is named after the Greek philosopher and mathematician Pythagoras who lived around 500 500 BCE.. Remember that a right triangle has a 90° Figure 9.12..

If a triangle is a right triangle, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. a 2 + b 2 = c 2 (eh squared , plus , b squared , equals , c squared , open p. 491) Proof on p. 497, Exercise 49; Theorem 8-2From Geometry, recall that the Pythagorean Theorem is a 2 + b 2 = c 2 where a and b are the legs of a right triangle and c is the hypotenuse. Also, the side opposite the angle is lower case and the angle is upper case. For example, angle A is opposite side a. Figure 1.1. 1. The Pythagorean Theorem is used to solve for the sides of a right triangle.6.1. The theorem 257 which isn’t an integer. (This triangle is our old friend, the 45-45-90 right triangle.) Or if we pick the hypotenuse to be 8 and one leg to be 5, then the other leg is given by 2 +52 = 82 =⇒ 2 +25 = 64. (6.4) Subtracting 25 from both sides of thisPythagoras theorem is: a2 +b2 = c2 a 2 + b 2 = c 2. Side c c is known as the hypotenuse, which is the longest side of a right-angled triangle and is opposite the right angle.
