Chapter 8 Right Triangles and Trigonometry. Theorem 8-1. Pythagorean Theorem. 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 8-2The Pythagorean theorem states that if a triangle has one right angle, then the square of the longest side, called the hypotenuse, is equal to the sum of the squares of the lengths of the two shorter sides, called the legs. So if a a and b b are the lengths of the legs, and c c is the length of the hypotenuse, then a^2+b^2=c^2 a2 +b2 = c2.The famous theorem by Pythagoras defines the relationship between the three sides of a right triangle. Pythagorean Theorem says that in a right triangle, the sum of the squares of the two right-angle sides will always be the same as the square of the hypotenuse (the long side).
