La médiatrice d’un segment est une droite qui est perpendiculaire à ce segment et qui passe par son milieu.
Il semble que d1d_{1} ne soit pas perpendiculaire à AB et que d3d_{3} ne passe pas par le milieu de AB.
Donc il ne reste que d2d_{2} qui semble bien perpendiculaire et passant par le milieu du segment AB.
