- Homework Statement
- Construct a quadrilateral in the poincare half-plane model, such that the sum of all its angles is less than 60 degrees.

- Relevant Equations
- n/a

I created the attached file in geogebra but I don't know how to come up with less than 60 degrees. There always seems to be at least one angle that is large, no matter how I manipulate the curves. Quadrilateral is points US(1)V(1)W. The attached does not include angle measures but I assume the idea is clear. Any help would be much appreciated!
