How to know when ambiguous case is no triangle

The video tutorial explains the ambiguous case of side-side-angle in triangle geometry, where one can have one, two, or no triangles. The teacher sets up a problem using given information and applies the law of sines to solve for angle B. Upon calculation, an error domain is encountered, indicating no triangle can exist. The teacher concludes with a visual explanation to illustrate why no triangle is possible in this scenario.

Describe how the visual representation of a triangle can help in understanding triangle formation.
