1. While other cases show only one solution by using the Law of Sines, SSA gives one or more solutions, or even no solution.
2. The law of sines may result in numerical error if an angle is close to 90 degrees.
3. sin A= h/b; sin B=h/a
h= bsin A=aSin B
Therefore: a/sin A=b/SinB
By using the same method with different altitude which is from angle A to side a, b/sin B=c/sin C
a/sin A=b/sin B=c/sin C
