Rule of sines

WebbIf you do change to Law of Sines, you can test your results by substituting ALL of your sides and angles into the proportion. If you do not obtain equivalent results, you have the extraneous solution and will need to rework the problem using the supplement of the angle you initially obtained.

Webb7 okt. 2024 · The law of sines is used to solve triangles in which you know only two angles and one of the opposing sides (called AAS for angle-angle-side), or two sides and one of the opposing angles (called SSA for side-side-angle). Why does the law of sines not always work? Cases when you can not use the Law of Sines Webb7 okt. 2024 · The Sine Rule can be used in any triangle (not just right-angled triangles) where a side and its opposite angle are known. You will only ever need two parts of the Sine Rule formula, not all three. You will need to know at least one pair of a side with its opposite angle to use the Sine Rule.
