The Law of Cosines states: [1] a² = b² + c² – 2bc cos (α) b² = a² + c² – 2ac cos (β) c² = a² + b² – 2ab cos (γ) Where: a, b, and c are the lengths of the triangle’s sides. α, β, and γ are the angles opposite to sides a, b, and c. If you know other properties of the triangle, you can solve the remaining sides and angles ...
