                      Arc

                      Reading time: 1min

                      Constructs an arc.

                      Syntax

                      arc(Point, Real, Real, Real)
                      
                      arc(Circumference, Real, Real)
                      
                      arc(Point, Point, Point, Real)
                      
                      arc(Line, Line, Real)
                      

                      Description

                      Given a point A, and three reals r, α and dα, constructs an arc with centre at point A, radius r, initial angle α and amplitude dα.

                      Given a circumference, and two reals α and dα, constructs an arc over the circumference with initial angle α and amplitude dα.

                      Given three points A, B and C, and a real r, constructs an arc with centre A and radius r between the lines passing through A, B and A, C.

                      Given two non-parallel lines and a real r, constructs an arc with center the intersection point between the lines, radius r, and enclosed the two lines.
