WebFor ABC shown above, ∠CAD is the exterior angle for ∠A and ∠B and ∠C are the two remote interior angles. We know that ∠CAB + ∠B + ∠C = 180°. Also, ∠CAB and ∠CAD form a straight angle, so ∠CAB + ∠CAD = 180°. Since both sums equal 180°: ∠CAB + ∠CAD = ∠CAB + ∠B + ∠C ∠CAD = ∠B + ∠C The same can be shown for any exterior angle of any triangle. Web(for all triangles) a2 + b2 − 2ab cos (C) = c2 So, to remember it: think " abc ": a2 + b2 = c2, then a 2 nd " abc ": 2ab cos (C), and put them together: a2 + b2 − 2ab cos (C) = c2 When to Use The Law of Cosines is useful for finding: the third side of a triangle when we know two sides and the angle between them (like the example above) WebIn a triangleABC a (cos^2B+cos^2C)+cosA (ccosC+bcosB) is equal to?
