Answer
The statement is false.
Work Step by Step
When multiplying a constant $\left( -1 \right)$ with a vector, the direction of the new vector and original vector will be opposite, but magnitude will be same. Hence, the direction of $\mathbf{E}$ and $-\mathbf{E}$ will be opposite but the magnitudes will be the same and similarly for $\mathbf{F}$.
From the given graph, the addition of two vectors is
$\begin{align}
& \mathbf{G}-\mathbf{F}=-\mathbf{A} \\
& \mathbf{B}-\mathbf{E}\ne -\mathbf{A} \\
\end{align}$
Therefore,
$\mathbf{B}-\mathbf{E}\ne \mathbf{G}-\mathbf{F}$
Both vectors do not equal in magnitude as well as direction due to which $\left( \mathbf{B}-\mathbf{E} \right)$ and $\left( \mathbf{G}-\mathbf{F} \right)$ are not equal.
Thus, the statement is false.
