AB et AM colinéaires si : AM= a*AB
Ici AB est un v.directeur

Deux d parr si leurs v.directeurs sont colinéaires
Il faut montrer que les v sont proportionnels

AM= a AB + b AC
Alors M est dans le plan ABC 
Marche avec vecteur pour coplanaire

Milieu AB = adition chaque coord /2

Distance AB = sqrt((xb-xa)^2 + etc)

Equation param :
  AM= x=xa+k*a
      y=ya+k*b
      z=za+k*c
      
a étant coordonée de A
a étant cordonnée v.directeur
