Considera un paralelogramo \(ABCD\) con \(A = [1,3]\), \(B = [2,-1]\) y \(C = [5,1]\). Sea \(S\) el centro de la diagonal \(BD\). Halla el vector \(\overrightarrow{AS } \).
\(\overrightarrow{AS } = (2,-1)\)
\(\overrightarrow{AS } = (2,1)\)
\(\overrightarrow{AS } = (1,3)\)
\(\overrightarrow{AS } = (-2,1)\)
