Teaching Triangle - Law of Sines Ambiguous Case

This model is a physical example of an ambiguous SSA (Side, Side, Angle) triangle.

A separate swinging arm can lock into two valid locations while maintaining two defined side lengths and one defined angle.

 

Customization

• Unlabeled - Simple triangle with no labeled dimensions
• Labeled - Example triangle with the values 15, 20, and 45 degrees
• Custom - Use the included Fusion file to easily create your own specific triangles with or without labels.

Printing

• No supports or brim required.
• If printing a labeled variation, consider swapping out your filament color mid-print to improve text legibility.
