Achtung: bei Kurve, Refexoin sind geometrische Beweise.

A = Intersect(xAxis, yAxis)
B = Point(xAxis)
c = Circle(A, B)
C = Point(c)
D, E = Intersect(c, xAxis)
a = Segment(E, C)
b = Segment(C, A)
E' = Mirror(E, b)
C' = Mirror(C, b)
a' = Segment(E', C')
d = Ray(C, E')
F = Intersect(d, xAxis)
α = Angle(A, E, C)
β = Angle(E, C, A)
γ = Angle(A, C, F)
δ = Angle(F, A, C)
H = Point(xAxis)
ε = Angle(H, F, E')
