Law of Cosines ಎಂದರೇನು?

The Law of Cosines relates the three sides of any triangle to one of its angles. It generalises the Pythagorean theorem: when the angle C = 90°, cos(C) = 0 and the formula reduces to a² + b² = c².

1. 1Label the triangle sides a, b, c and opposite angles A, B, C
2. 2To find side c: c² = a² + b² − 2ab·cos(C)
3. 3To find angle C: cos(C) = (a² + b² − c²) / 2ab
