Law of Sines :: The Ambiguous Case State the number of possible triangles that can be formed using the given measurements. The document is a worksheet on the Law of Sines, focusing on the ambiguous case in triangle formation. Given the triangular parts SSA, however, is different and leaves the triangle unclear, The law of sines is important, because it can be used to solve problems involving both right and non-right triangles, because it involves only the sides and angles of a triangle. Write down known. These worksheets explain how to In the following example you will find all the possible measures of an angle of a triangle using Law of Sines. Draw and label a figure. For problems in which we use the Law of sines given one angle and two sides, there may be one possible triangle, two possible triangles Ambiguous Triangles Given triangular parts SSS, ASA or AAS always guarantees a single, unique triangle.
