# Drawing vector summation parallelogram with TiKZ

I'd like to draw something like this:

With two sides labeled, and the ability to label all four vertices, using TiKZ. How can this be done?

• You \draw[->](0,0)--node[auto]{$v_{ab}$}(2,3); to draw an arrow with a label. Dec 9, 2020 at 3:05

\documentclass[tikz,border=3mm]{standalone}
{ (O) edge[\X,-latex,edge label={$v_{\Z}$}] (\Y)}
