Summary edit

Description

Arriving at the solution of minimizing total distance from a point to the three vertex of a given triangle(Fermat's Problem) : Rotate one side of the triangle with the arbitary point F for 60 degrees, and the distance to minimize is the shortest path from A to D. Hence the solution is when it become a straight line.

Instruction edit

  1. Run eukleides and compile it into en:PSTricks.
  2. Paste the resulting code in the following en:TeX file and compile it into eps.
\documentclass{article}
\usepackage{pstricks}
\usepackage{color}

\begin{document}
\pagestyle{empty}
\colorbox{white}{

%Paste the code here

}
\end{document}
  1. Import the eps file using en:Scribus. (Remember to install en:ghostscript also and configure the path to ghostscript correctly in Scribus's Preferences)
  2. And then export it to en:svg.
  3. Post-process using en:Inkscape.
