M1 for \(\begin{pmatrix} 4 \\ -2 \end{pmatrix}\) or for \(\begin{pmatrix} 3 \\ 2 \end{pmatrix} + \begin{pmatrix} 1 \\ -4 \end{pmatrix}\) correctly drawn in an incomplete vector triangle with or without arrows
Could be part of a complete vector triangle
For 2 or 1 marks allow correct vector drawn when construction/counting lines/arcs are drawn.
