WebThe Law of Cosines 709 Lesson 10-8 The Law of Cosines (a2 + b2 - 2abcos C = c2) is the Pythagorean Theorem (a 2 + 2b = c) with an extra term, –2ab cos C.Consider three different triangles: If ∠C is acute, as in Example 1, then cos C is positive and the extra term, –2ab cos C, is negative. So c 2 < a2 + b. If ∠C is obtuse, as in Example 3, then cos C is negative and … WebTherefore, AB 2 + AC 2 = BC 2, since CBDE is a square. This proof, which appears in Euclid's Elements as that of Proposition 47 in Book 1, demonstrates that the area of the square on the hypotenuse is the sum of the areas of the other two squares.
