A = (3, 10)
B = (11, 10)
C = (13, 14)
D = (5, 14)
Vieleck1, a, b, c, d = Polygon(A, B, C, D)
E = Point(a)
e = Line(D, C)
f = OrthogonalLine(E, e)
F_1 = Intersect(f, a)
G = Intersect(e, f)
g = Segment(D, G)
h_a = Segment(E, G)
h = Line(A, D)
F = Point(b)
i = OrthogonalLine(F, h)
I = Intersect(i, h)
J = Intersect(h, b)
h_b = Segment(I, F)
k = Segment(I, D)
