Expressing h B in terms of the side and the sine of the angle will lead to the formula of the sine law. sin A = h B c. h B = c sin A. sin C = h B a. h B = a sin C. Equate the two h B 's above: h B = h B. c sin A = a sin C. WebMar 9, 2024 · Generally, there are several ways to prove the Law of Sines and the Law of Cosines, but I will provide one of each here: Let ABC be a triangle with angles A, B, C and sides a, b, c, such that angle A subtends side a, etc. Theorem (Law of Sines). Sin [A]/a = Sin [B]/b = Sin [C]/c. Proof. Draw the perpendicular (altitude) from B to side b, and ... cipher\u0027s 67
