[Tex/LaTex] Drawing thick, doublesided arrows with texts between circles

tikz-pgf

This is the first time I'm using Latex to draw things, so this is all new to me.

I'm trying to draw the following

enter image description here

And I got the circles about right, but I have no idea how to draw these arrows:

enter image description here

This is my code:

\begin{tikzpicture}
\def\firstcircle{(0,0) circle (2cm)}
\def\secondcircle{(6,-8) circle (2cm)}
\def\thirdcircle{(12,0) circle (2cm)}
\begin{scope}[ fill opacity=0.8]
    \fill[red] \firstcircle;
    \fill[green] \secondcircle;
    \fill[blue] \thirdcircle;
\end{scope}

\draw \firstcircle node[] (c1) {Verwacht};
\draw \secondcircle node[] (c2) {Afspraak};
\draw \thirdcircle node[] (c3) {Geleverd};
\draw[<->] (c1) -- (c2);
\draw[<->] (c2) -- (c3);
\draw[<->] (c3) -- (c1);
\end{tikzpicture}

If anyone could help me with these arrows, thanks!

With arrows.meta from tikz v3.

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{arrows.meta}
\begin{document}
  \begin{tikzpicture}
      \node[fill=red,circle,minimum width=1cm] at (0,0) (c1) {Verwacht};
      \node[fill=blue,circle,minimum width=1cm] at (5,0) (c2) {Afspraak};
      \node[fill=green,circle,minimum width=1cm] at (2.5,-4) (c3) {Geleverd};
      \draw[draw=red!60!black,line width=12pt,{Latex[length=9mm]}-{Latex[length=9mm]}] (c1)  -- (c2) 
         node[midway,text=white,font=\footnotesize\bfseries]{tevreden};
      \draw[draw=red!60!black,line width=12pt,{Latex[length=9mm]}-{Latex[length=9mm]}] (c2) -- (c3) 
         node[midway,text=white,font=\footnotesize\bfseries,sloped]{betrouwbaar};
\draw[draw=red!60!black,line width=12pt,{Latex[length=9mm]}-{Latex[length=9mm]}] (c3) -- (c1) 
         node[midway,text=white,font=\footnotesize\bfseries,sloped]{duidelijk};
  \end{tikzpicture}
\end{document}

Without arrows.meta (should work with tikz v2.1)

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{arrows}
\begin{document}
  \begin{tikzpicture}
    \node[fill=red,circle,minimum width=1cm] at (0,0) (c1) {Verwacht};
    \node[fill=blue,circle,minimum width=1cm] at (5,0) (c2) {Afspraak};
    \node[fill=green,circle,minimum width=1cm] at (2.5,-4) (c3) {Geleverd};
    \draw[draw=red!60!black,line width=10pt,stealth-stealth] (c1)  -- (c2) 
        node[midway,text=white,font=\footnotesize\bfseries]{tevreden};
    \draw[draw=red!60!black,line width=12pt,stealth-stealth] (c2) -- (c3)
        node[midway,text=white,font=\footnotesize\bfseries,sloped]{betrouwbaar};
    \draw[draw=red!60!black,line width=12pt,stealth-stealth] (c3) -- (c1)
        node[midway,text=white,font=\footnotesize\bfseries,sloped]{duidelijk};
   \end{tikzpicture}
\end{document}

Finally, it all boils down to the selection/design of arrow tips. While tikz v3 offers numerous possibilities, those with v2.1 are limited. Choose an arrow type as per your taste.

I am definitely unfamiliar with both beamer and tikz (do not quite get what the \only are supposed to do) but perhaps this could go in the direction you want:

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{chains}
\newcounter{count}

% helper macro:
\long\def\GobToSemiColon #1;{}

\newcommand\myPicture{
\begin{tikzpicture}
  \begin{scope}[start chain = going below]
  \ifnum\value{count}<1 \expandafter\GobToSemiColon\fi
  \ifnum\value{count}>3 \expandafter\GobToSemiColon\fi
  \node[draw, rectangle, on chain] {display only when counter is between
    1 and 3};

  \ifnum\value{count}>-1 \expandafter\GobToSemiColon\fi
  \node[draw, rectangle, on chain] {display only when counter is
    negative}; 

  \ifnum\value{count}<100 \expandafter\GobToSemiColon\fi
  \ifnum\value{count}>200 \expandafter\GobToSemiColon\fi  
  \node[draw, rectangle, on chain] {display only if counter is between
    100 and 200};

  \ifnum\value{count}<3 \expandafter\GobToSemiColon\fi
  \ifnum\value{count}>20 \expandafter\GobToSemiColon\fi
  \node[draw, circle, on chain] {only when counter is in the range 3 to 20};
  \end{scope}
\end{tikzpicture}
}

\begin{document}
\begin{frame}
\only{\setcounter{count}{-3}\myPicture}
\only{\setcounter{count}{105}\myPicture}
\only{\setcounter{count}{39}\myPicture}
\only{\setcounter{count}{2}\myPicture}
\only{\setcounter{count}{5}\myPicture}
\end{frame}
\end{document}

[Tex/LaTex] TikZ: Drawing an arc from an intersection to an intersection

A solution which allows to draw intersection segments of any two intersections is available as tikz library fillbetween.

This library works as general purpose tikz library, but it is shipped with pgfplots and you need to load pgfplots in order to make it work:

\documentclass{standalone}

\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{fillbetween}

\begin{document}

\begin{tikzpicture}

\draw [name path=red,red] (120:1.06) circle (1.9);
%\draw [name path=yellow,yellow] (0:1.06) circle (2.12);
\draw [name path=green,green!50!black] (0:0.77) circle (2.41);
\draw [name path=blue,blue] (0:0) circle (1.06);

% substitute this temp path by `\path` to make it invisible:
\draw[name path=temp1, intersection segments={of=red and blue,sequence=L1}];
\draw[red,-stealth,ultra thick, intersection segments={of=temp1 and green,sequence=L3}];

\end{tikzpicture}

\end{document}

enter image description here

The key intersection segments is described in all detail in the pgfplots reference manual section "5.6.6 Intersection Segment Recombination"; the key idea in this case is to

create a temporary path temp1 which is the first intersection segment of red and blue, more precisely, it is the first intersection segment in the Left argument in red and blue : red. This path is drawn as thin black path. Substitute its \draw statement by \path to make it invisible.
Compute the desired intersection segment by intersecting temp1 and green and use the correct intersection segment. By trial and error I figured that it is the third segment of path temp1 which is written as L3 (L = left argument in temp1 and green and 3 means third segment of that path).

The argument involves some trial and error because fillbetween is unaware of the fact that end and startpoint are connected -- and we as end users do not see start and end point.

Note that you can connect these path segments with other paths. If such an intersection segment should be the continuation of another path, use -- as before the first argument in sequence. This allows to fill paths segments:

\documentclass{standalone}

\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{fillbetween}

\begin{document}

\begin{tikzpicture}

\draw [name path=red,red] (120:1.06) circle (1.9);
%\draw [name path=yellow,yellow] (0:1.06) circle (2.12);
\draw [name path=green,green!50!black] (0:0.77) circle (2.41);
\draw [name path=blue,blue] (0:0) circle (1.06);

% substitute this temp path by `\path` to make it invisible:
\draw[name path=temp1, intersection segments={of=red and blue,sequence=L1}];
\draw[red,fill=blue,-stealth,ultra thick, intersection segments={of=temp1 and green,sequence=L3}]  
    [intersection segments={of=temp1 and green, sequence={--R2}}]
;

\end{tikzpicture}

\end{document}
