5. Sine law

6. Sine law Given any triangle, the sine law can be used if you know
two sides and one angle opposite a given side (SSA) or
two angles and any side (AAS or ASA)

7. Sine law - AMBIGUOUS CASE
The ambiguous case arises in a SSA (side, side, angle) triangle.
In this situation, depending on the size of the angle and the lengths of the sides, the sine law calculation may lead to 0, 1, or 2 solutions.
