Another question: you can make an angle as small as you want by making its sides almost coincide. How else could you make the angle small? How small can you make it?
| Experiment with the angle sketch and compare the Poincaré measure
of an angle with its Euclidean measure (from the Sketchpad Measure
menu). Is one consistently bigger than the other? Are they ever
equal?
