Faire varier la position du point M

A = Intersect(xAxis, yAxis)
B = Point(xAxis)
C = Point(yAxis)
D = (8, 6)
a = Segment(C, A)
b = Segment(A, B)
c = Segment(B, D)
M = Point(b)
d = Segment(C, M)
e = Segment(D, M)
l: d + e
M': (x(M), l)
f = Segment(A, M)
T1: "Longueur tuyaux : " + l + ""
T2: "Distance AM : " + f + ""
