# figure 2 for Crossed Ladders Problem

I'd like to draw triangle like the following: but using the following code which produces: The code must represent the structure of the triangle, like that: \documentclass[tikz,border=2pt]{standalone} \usetikzlibrary{intersections,arrows.meta} \usepackage{siunitx}

    \begin{document}

\begin{tikzpicture}
\draw   (0,0) -- (5,0) -- (5,5) -- (5.5,5);
\draw[name path=A] (0,0)coordinate(o) -- (5,4.5)node[pos=0.8,sloped,auto]{$l_2=\SI{10}{\meter}$};
\draw[name path=B] (0,3) -- (5,0)node[pos=0.1,sloped,auto]{};
\path[name intersections={of=A and B,by={a}}];
\draw[dashed] (a)node[right=1mm]{M} -- (a|-o)node[pos=0.7,auto]{$R=\SI{3}{\meter}$}
coordinate[pos=1](a);
\coordinate (o) at (0,-0.5);
\draw[|<->|] (0,-0.5) -- node[below]{$d_1$} (a|-o);
\draw[|<->|] (0,-1) -- node[below]{$d$} (5,-1);
\draw[|<->|] (5.5,0) -- node[right]{$R_2$} (5.5,4.5);
\end{tikzpicture}

\end{document}


so i can't manage any help would be appreciated

• And your question is ...? – Svend Tveskæg Jan 29 '15 at 16:06
• Why can't you just adapt the code provided in the answer to your other question? You've posted code here which seems to be just the same code you posted earlier for your other question. The site is not intended to have people draw figure after figure for you. You need to try to understand the code and draw what you need yourself. – cfr Jan 29 '15 at 16:09
• its not the same code that i post it in other post check it – Educ Jan 29 '15 at 16:10
• The figure here is simpler than the one you already got an answer to. So, start with the code for the more complex diagram and remove the parts which are not necessary in order to create this one. – cfr Jan 29 '15 at 16:10
• There is a lot of good examples in the book tikz-euclid that you can find here: msenux.redwoods.edu/math/workshops/LatexWorkshop/docs/… and altermundus.fr/downloads/documents/Sangaku.pdf – Arne Timperman Jan 29 '15 at 17:09

Use \path instead of \draw for the "ladder" which shouldn't be drawn: \documentclass[tikz,border=2pt]{standalone}
\usetikzlibrary{intersections,arrows.meta}
\usepackage{siunitx}

\begin{document}

\begin{tikzpicture}
\draw   (0,0) -- (5,0) -- (5,5) -- (5.5,5);
\draw[name path=A] (0,0)coordinate(o) -- (5,4.5)node[pos=0.8,sloped,auto]{$l_2=\SI{10}{\meter}$};
\path[name path=B] (0,3) -- (5,0)node[pos=0.1,sloped,auto]{};
\path[name intersections={of=A and B,by={a}}];
\draw[dashed] (a)node[right=1mm]{M} -- (a|-o)node[pos=0.7,auto]{$R=\SI{3}{\meter}$}
coordinate[pos=1](a);
\coordinate (o) at (0,-0.5);
\draw[|<->|] (0,-0.5) -- node[below]{$d_1$} (a|-o);
\draw[|<->|] (0,-1) -- node[below]{$d$} (5,-1);
\draw[|<->|] (5.5,0) -- node[right]{$R_2$} (5.5,4.5);
\end{tikzpicture}

\end{document}
