Voor dit parallellogram geldt : $https://latex.codecogs.com/png.image?\dpi{110}(\, \overrightarrow{M}=\overrightarrow{OM}\: )$	A. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac12 \overrightarrow{AC}$
B. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac12 (\overrightarrow{A}+\overrightarrow{B})$
C. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac13 (\overrightarrow{A}+\overrightarrow{B}+\overrightarrow{C})$
D. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac14 (\overrightarrow{A}+\overrightarrow{B}+\overrightarrow{C})$
E. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac12 \overrightarrow{C}$

For this parallellogram, you can conclude that :	A. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac12 \overrightarrow{AC}$
	B. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac12 (\overrightarrow{A}+\overrightarrow{B})$
	C. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac13 (\overrightarrow{A}+\overrightarrow{B}+\overrightarrow{C})$
	D. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac14 (\overrightarrow{A}+\overrightarrow{B}+\overrightarrow{C})$
	E. $https://latex.codecogs.com/png.image?\dpi{110}\overrightarrow{M}=\frac12 \overrightarrow{C}$

$https://latex.codecogs.com/png.image?\dpi{110}\\\overrightarrow{M}=\frac12\overrightarrow{B}=\frac12(\overrightarrow{A}+\overrightarrow{C})\cdots staat\;niet\;bij\;de\;alternatieven\\\text{Dan proberen we de meest waarschijnlijke formule :}\\\frac14(\overrightarrow{A}+\overrightarrow{B}+\overrightarrow{C})=\frac14(\overrightarrow{B}+\overrightarrow{B})=\frac14.2\overrightarrow{B}=\frac12\overrightarrow{B}=\overrightarrow{M}$
