The video tutorial discusses the ambiguous case of side-side-angle in triangles, explaining how it can result in one, two, or no triangles. The teacher uses the law of sines to solve for a missing angle and demonstrates how to identify when no triangle exists due to an error domain. The tutorial also covers conditions under which one or two triangles can exist, emphasizing the importance of understanding these concepts in trigonometry and geometry.
