Bonjour ,pouvez-vous m'aidez à faire mon exercice de mathématiques svp?
On considère la figure ci-contre sur laquelle les droites (DE) et (AB)
sont parallèles. De plus, le point G appartient à la droite (DE) et les
droites (BC) et (AG) se coupent en H.
On donne : CD = 2 cm ; DA = 8 cm ; DE = 1,5 cm ;
AH = 6 cm ; HB = 4,5 cm ; EH = 5,5 cm.
1) Prouver que AB = 7,5 cm.
2) Calculer la longueur EG.
3) Démontrer que le triangle ABH est rectangle.
merci
