In trigonometry, the law of cosines (also known as the cosine formula, cosine rule, or al-Kashi's theorem ) relates the lengths of the sides of a triangle to the cosine of one of its angles. Using notation as in Fig. 1, the law of cosines states where γ denotes the angle contained between sides of lengths a and b and opposite the side of length c. For the same figure, the other two relations are … WebAlternatively, you can go back to the law of cosines derivation and use the fact that if a → and b → are perpendicular, then a → ⋅ b → = 0 . ( a − b) 2 for numbers ¶ If γ = 0, then the triangle is flat, and it's a bit questionable whether we can still call it a triangle.
