Question: In my below MWE, i just want to change the style of arrows (in all possible ways) on every lines.


\begin{tikzpicture}[line cap=round,line join=round,>=triangle 45,x=1cm,y=1cm]
\draw [line width=0.3pt] (0,0)-- (0,4);
\draw [line width=0.3pt] (0,0)-- (4,0);
\draw [line width=0.3pt] (0,4)-- (4,4);
\draw [line width=0.3pt] (4,4)-- (4,0);
\draw [line width=0.3pt] (4,0)-- (10,0);
\draw [line width=0.3pt] (10,0)-- (10,4);
\draw [line width=0.3pt] (10,4)-- (7,2);
\begin{scope}[very thick,decoration={
    mark=at position 0.5 with {\arrow{>}}}
\draw [line width=0.3pt,postaction={decorate}] (0,0)-- (0,4);
%\draw [line width=1pt,postaction={decorate}] (0,0)-- (4,4);(this command create arrow with line segment)
\draw [line width=0.3pt,postaction={decorate}] (4,4)-- (0,4);
\draw [line width=0.3pt,postaction={decorate}] (4,0)-- (0,0);
\draw [line width=0.3pt,postaction={decorate}] (4,0)-- (10,0);
\draw [line width=0.3pt,postaction={decorate}] (10,0)-- (10,4);
\draw [line width=0.3pt,postaction={decorate}] (7,2)-- (10,4);
\draw [fill=black] (0,0) circle (2pt);
\draw[color=black] (-0.0437,-0.42) node {$V_2$};
\draw [fill=black] (0,4) circle (2.5pt);
\draw[color=black] (-0.0437,4.4) node {$V_1$};
\draw [fill=black] (4,0) circle (2.5pt);
\draw[color=black] (3.97592,-0.42) node {$V_3$};
\draw [fill=black] (4,4) circle (2.5pt);
\draw[color=black] (3.97592,4.4) node {$V_4$};
\draw [fill=black] (10,0) circle (2.5pt);
\draw[color=black] (9.96542,-0.42) node {$V_5$};
\draw [fill=black] (10,4) circle (2.5pt);
\draw[color=black] (9.96542,4.42) node {$V_6$};
\draw [fill=black] (7,2) circle (2.5pt);
\draw[color=black] (6.93074,1.60589) node {$V_7$};

  • I understand that you want to change the arrow style, if my assumption is correct, in the provided link, the OP showed many arrow styles, so only I suggested that. Is anything wrong in this? Please advise.... – MadyYuvi Aug 28 at 7:10
  • @MadyYuvi Nothing wrong. I accepted your suggestion but the problem is i dont have good command in latex drawing in fact in tikz that is why i am telling you that do some correction in above codes. – Maths4Sandy Aug 28 at 8:08
