With three angles only, a triangle is uniquely constructible?
With three angles only, a triangle is uniquely constructible?
- ayes, always
- bno — only similar triangles result
- conly for right-angled cases
- donly for equilateral cases

Three angles only fix the shape but not the size, since the angle sum leaves the side lengths free to scale. This produces infinitely many similar (but not congruent) triangles, so a unique triangle cannot be constructed.
