aidez moi svp! :D A(+8) ; B(-2) ; C(-7) ; D(+12) Calculer la distance AB , AC , AD , BC , BD et CD

Bonsoir,

Pour calculer la distance entre deux points, on calcule la différence suivante : la plus grande abscisse - la plus petite abscisse.

AB = (+8) - (-2) = 8 + 2 = 10
AC = (+8) - (-7) = 8 + 7 = 15
AD = (+12) - (+8) = 12 - 8 = 4
BC = (-2) - (-7) = -2 + 7 = 5
BD = (+12) - (-2) = 12 + 2 = 14
CD = (+12) - (-7) = 12 + 7 = 19
