Arc

arc(Point, Real, Real, Real)

arc(Circumference, Real, Real)

arc(Point, Point, Point, Real)

arc(Line, Line, Real)

Given a point $A$, and three reals $r$, $\alpha$ and $d\alpha$, constructs an arc with centre at point $A$, radius $r$, initial angle $\alpha$ and amplitude $d \alpha$.

Given a circumference, and two reals $\alpha$ and $d \alpha$, constructs an arc over the circumference with initial angle $\alpha$ and amplitude $d \alpha$.

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.
