Law of Cosines | Let ∆ABC by a triangle with a, b, and c representing the measures of sides opposite the angles with measures A, B, and C respectively. Then the following equations are true, a^2 = b^2 + c^2 – 2bc ·cos A, b^2 = a^2 + c^2 – 2ac ·cos B, and c^2 = a^2 + b^2 – 2ac ·cos C. |
Law of Sines | Let ∆ABC by a triangle with a, b, and c representing the measures of sides opposite the angles with measures A, B, and C respectively. Then, sin A/a = sin B/b = sin C/c. |
