Question

$ABCD$ is a square, and $M$ and $N$ are the midpoints of $BC$ and $CD$ respectively. Express $\overrightarrow{AB}$, $\overrightarrow{AC}$ and $\overrightarrow{BD}$ in terms of $\mathbf{p}$ and $\mathbf{q}$, where $\overrightarrow{AM}=\mathbf{p}$ and $\overrightarrow{AN}=\mathbf{q}$.

Accepted Answer

AB = (4/3)p - (2/3)q; AC = (2/3)(p+q); BD = 2(q-p)
