# TikZ: Can a node be placed at pos = .5 and then a coordinate at the end of the line?

As the title say, can a node and a coordinate be placed on the same line?

\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\coordinate (P1) at (-2, 0);
\coordinate (P2) at (2, 0);
\draw (P1) -- (P2);
\draw[-latex] (P1) -- ++(-88.2036:1.75cm) node[scale = .75, pos = .5,
fill = white, shape = circle, inner sep = 0cm] {$$\nu_2$$};
\draw[-latex](P1) -- ++(-20:5cm) node[scale = .75, pos= .5,
fill = white, inner sep = 0cm, shape = circle] {$$v_2 = 12.9005$$};
\end{tikzpicture}
\end{document}


Can I add a coordinate to end of (P1) -- ++(-88.2036:1.75cm)? I couldn't find anything with a search or in the manual.

You can add a coordinate directly after the node or directly before it.

## Code

\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\coordinate (P1) at (-2, 0);
\coordinate (P2) at (2, 0);
\draw (P1) -- (P2);
\draw[-latex] (P1) -- ++(-88.2036:1.75cm)
node[scale = .75, pos = .5, fill = white, shape = circle, inner sep = 0cm] {$$\nu_2$$}
coordinate (here);
\draw[-latex] (P1) -- ++(-20:5cm)
coordinate (there)
node[scale = .75, pos= .5, fill = white, inner sep = 0cm, shape = circle] {$$v_2 = 12.9005$$};
\draw[blue] (here) -- (there);
\end{tikzpicture}
\end{document}
