Graphics, Figures & Tables ⇒ PSTricks | Draw Line with relative Angle to another

[svend_tveskaeg]

Hi all.

Consider the following MWE:

Code: Select all

\documentclass{article}
\usepackage{auto-pst-pdf,pst-node}

\begin{document}

\begin{pspicture}
\pnode(0,0){A}
\pnode(4,0){B}
\psline(A)(B)
\end{pspicture}

\end{document}

I compile with

Code: Select all

pdflatex -shell-escape <filename>.tex

Now to my problem: I would like to draw a line from node A, making a 45 degrees angle with the line from node A to node B, of length 5 (or some other length --- it does not matter).

I have tried \psline(A)([angle=45]A) (and other things) but I could not figure out how to do it without having specific coordinates for the other end of the line I want do draw.

How do I do this?

Thank you in advance!

\psdot(C)
\psarc[linestyle=dashed](0,0){5}{0}{50}
