Given a certain curve, or part of a circle, how do you express how much it is bent?
If I have for example 1/3 of a circle (without seeing the full circle). How do I calculate and express that it is bent in a way that it forms 1/3 of a circle.
And as a follow-up on this question, how can I then construct the full circle, from this data.
Excuse me if it is unclear, it's hard for me to explain this in English.
