Bonjour,
A(1,0)
DM=2/3 DC
MC=DC-DM
MC= DC-2/3DC
MC= DC(1-2/3)
MC=1/3DC
DC=-CD
CM=-MC
-MC=-1/3CD
CM=1/3CD
CD=AB
CM=1/3 AB
M(1/3,1)

BP=3/2BC
P(0.3/2)

AM( 1/3-1=-2/3 )
(1-0=1)
AM(-2/3,1)

AP (0-1=-1)
(3/2-0=3/2)
AP( -1:3/2)

je remarque que
(-2/3)(3/2)=-1
(1)(3/2)=3/2
d'où
AMx3/2=AP
AP=3/2AM
APet AM colinéaires
comme A∈AP et AM
A, M et P alignés
