An Arc2d is a section of a circle, defined by its center point, start point and swept angle (the counterclockwise angle from the start point to the end point). This module includes functionality for

• Constructing arcs through given points and/or with a given radius
• Scaling, rotating, translating and mirroring arcs
• Converting arcs between different coordinate systems

You are unlikely to need to use these functions directly, but they are useful if you are writing low-level geometric algorithms.
