Eigenschaften der Ellipse

F_1 = Point(xAxis)
F_2 = Point(xAxis)
e = Ellipse(F_1, F_2, 5)
P = Point(e)
A = Intersect(e, xAxis, 1)
B = Intersect(e, xAxis, 2)
C = Intersect(e, yAxis, 1)
D = Intersect(e, yAxis, 2)
M = Intersect(xAxis, yAxis)
a = Segment(A, M)
b = Segment(M, C)
d = Segment(F_1, C)
x_1 = Segment(F_1, P)
x_2 = Segment(P, F_2)
c: x_1 + x_2
f = Segment(M, F_2)
