We have been learning about SSA abiguity the last few days. SSA is ambiguous because there can be more than one triangle. You cannot just apply the law of sines because first you need to determine whether there are two, one, or zero triangles. You need to find the amplitude. If side a is more than side b there is only one triangle. If side a is less than side b and more than the amplitude, there are two triangles. If side a is less than h, there aren't any triangles. If i had to teach someone SSA ambiguity, I would draw diagrams and do example problems.
