解：（1）当该角为已知边所夹时，三角形唯一；（2） 当不是已知边所夹时 (i) 若已知角大于等于90度，三角形唯一，(ii) 若已知角为锐角时三角形不唯一（有两种情况）。
The Ambiguous Case (SSA)When you are given two sides of a triangle and an angle opposite one of them,you may find that the triangle is not unique. Some information may result in twotriangles, and some may result in no triangle at all. It is because of this that thecase of knowing tw...

Given two triangle sides and one angle If the angle is between the given sides, you can directly use the law of cosines to find the unknown third side, and then use the formulas above to find the missing angles, e.g. given a,b,γ: calculate c=a2+b2−2ab×cos(γ)c=a2+b2...
How to find the angle? Example Let's show how to find the sides of a right triangle with this tool: Assume we want to find the missing side given area and one side. Select the proper option from the list. It's the third one. Type in the given values. For example, the area of ...

How do you use the Side-Angle-Side Theorem? The SAS Theorem states thatif two sides and their included angle are given for two triangles, and these aspects are identical for both triangles, then the triangles are congruent. To apply the SAS postulate, verify the known sides and the included...
