For … 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 …
