Instructions.
Il est possible de déplacer les points
\(A,B\) et
\(C\) afin de changer les vecteurs. Pour ce faire, maintenir la souris au-dessus d’une lettre. Des flèches devraient apparaitre. Un clic simple sur la lettre permet de changer la direction du mouvement alors qu’un clic maintenu et un déplacement permettent de bouger la figure.
