Question:
\begin{minipage}{0.45\linewidth}
Tenemos un hexágono regular $ABCDEF$ cuyo centro es $S$ y la longitud de su arista es $1$. En el hexágono, los vectores $\vec a$, $\vec b$, $\vec c$, $\vec d$ y $\vec e$ se han resaltado (observa la figura). Calcula el producto escalar de cada par de vectores dados y empareja el resultado de cada producto con su valor correcto.
