The Law of Sines states that in every triangle the … Web6 aug. 2015 · If α ≥ 90 ° and a > b, there is 1 triangle. If α < 90 ° and a < b sin α, there are 0 triangles. If α < 90 ° and a = b sin α, there is 1 triangle, and β = 90 °. If α < 90 ° and b sin α < a < b, there are 2 triangles, and the two possible values of β are supplementary. If α < 90 ° and b ≤ a, there is 1 triangle.
Web28 jan. 2014 · The two places are points on side c, which is of unknown length, and we can swing side b because Angle C is unknown. The SSA case uses the law of sines as you mentioned. You have to find all the angles first, the first with law of sines and the second with the triangle sum theorem (i think I just made up that name). That is, angle C=180-A-B.
