163 Soit \( A B C \) un triangle. Soit I le milieu du segment \( [A C] \) et \( G \) le point tel que: \[ \overrightarrow{G A}+2 \overrightarrow{G B}+\overrightarrow{G C}=\overrightarrow{0} \] 1. a. À l'aide de la relation de Chasles, montrer qu'on a l'éaglité \( 2 \overrightarrow{G B}+\overrightarrow{G C}=-3 \overrightarrow{A G}+2 \overrightarrow{A B}+\overrightarrow{A C} \).
