GE // AM

\(\Rightarrow\frac{GE}{AM}=\frac{BE}{BM}\) ( Định lý Ta-lét )

Tương tự \(\frac{FE}{AM}=\frac{CE}{CM}=\frac{CE}{BM}\) ( Vì CM = CM )

Cộng các vế hai đẳng thức trên ta có : \(\frac{GE}{AM}+\frac{FE}{AM}=\frac{BE}{BM}+\frac{CE}{BM}\)

\(\Rightarrow\frac{FE+EG}{AM}=\frac{BC}{BM}=2\)

\(\Rightarrow FE+EG=2AM\)
