Bonjour,
1)
a) CM = CB + BM
= -BC + 1/2AB
b) CN = CA + AN
= CA + 3AD
= (CD + DA) + 3AD
= CD - AD + 3AD
= 2AD - DC
2) Si ABCD est un parallélogramme : AB = DC et AD = BC
donc : CN = 2AD - DC
= 2BC - AB car AD = BC et DC = AB
= -2(AB/2 - BC)
= -2CM
Dans ce cas, CM et CN sont colinéaires, donc C, M et N sont alignés
