make EH=GE  GH=2×GE=BG  ⇒BG^(→) =GH^(→)   CG^(→) =HA^(→)   AG^(→) +BG^(→) +CG^(→) =AG^(→) +GH^(→) +HA^(→) =0
$${make}\:{EH}={GE} \\ $$$${GH}=\mathrm{2}×{GE}={BG} \\ $$$$\Rightarrow\overset{\rightarrow} {{BG}}=\overset{\rightarrow} {{GH}} \\ $$$$\overset{\rightarrow} {{CG}}=\overset{\rightarrow} {{HA}} \\ $$$$\overset{\rightarrow} {{AG}}+\overset{\rightarrow} {{BG}}+\overset{\rightarrow} {{CG}}=\overset{\rightarrow} {{AG}}+\overset{\rightarrow} {{GH}}+\overset{\rightarrow} {{HA}}=\mathrm{0} \\ $$
