Bài 1: Cho G là trọng tâm của \(_{\Delta}\) DEF+ DH,EK .Điền vào (........)
a,EG=..........................................................EK
GK=............................................................EK
GK=...........................................................EG
b,DH=.......................................................DG
DH=..........................................................GH
DG=..........................................................GH
Giúp mình với cho 1 like
a/EG=\(\dfrac{2}{3}\)EK
GK=\(\dfrac{1}{3}\)EK
GK=\(\dfrac{1}{2}\)EG
b/DH=\(\dfrac{3}{2}\)DG
DH=3GH
DG=2GH
