Arc

Constructs an arc.

arc(Point, Real, Real, Real)

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

arc(Circumference, Real, Real)

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

arc(Point, Point, Point, Real)

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

arc(Line, Line, Real)

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.
