I think this is a good question for tex.stackexchange.com . You will, as
Herbert said, need to say what you include in the full preample, because
without that it is hard to guess what the problem might be.
One way to solve the problem, though possibly not what you are after, is to
create a pdf of the figure first and include this compiled pdf as a figure
in your document. You can do this with the standalone package, code below.
When you insert the compiled pdf figure in your document, you need the
\begin{figure}
\includegraphics{figure}
\caption{}
\end{figure}
Here is the code for the figure to be compiled separately.
\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (-0.5, 0) -- (7.5,0) ; % horiz segment
\filldraw (0,0) circle (2pt) node[anchor=north east] {A}; % label point
(0,0) as A
\filldraw (7,0) circle (2pt) node[anchor=north west] {B}; % label point
(7,0) as B
\draw [dotted] (0,0) -- (50:9);
\filldraw (50:9) circle (2pt) node [anchor= north west] {$C$}; %
draw diagonal segment
\foreach \i in {1,...,7} % place dots along diagonal
\filldraw (50:\i) circle (2pt) node [anchor=south east] {\i};
\draw [dashed] (7,0) -- (50:7); % draw segment from 7 to B
% draw lines through 1, 2,..., 6 parallel to line from 7 to B
\foreach \m in {1,...,6}
\draw (50:\m) -- (\m, 0);
\foreach \t in {1,...,6} % label the points n/7
\filldraw [red] (\t,0) circle (2pt) node [below] {\t/7};
% describe construction process
\draw [xshift=6.8cm, yshift=5cm]
node[right, text width = 7.5cm,fill=green!20]
{The points are constructed as follows:\\
\hspace*{9pt}First the segment $A$ to $B$ is drawn so that the
distance from $A$ to $B$ is 1 unit
of length. Next construct the diagonal segment from $A$ to $C$
which we will denote by
$\mathcal{S}$. Then along $\mathcal{S}$ construct the points
labelled $1,\dots,7$ so that if $d$ is
the distant from $A$ to 1, then the distance from $n$ to $n+1$ is
also $d$ --- use compass!\\
\hspace*{9pt}Now the dashed segment from 7 to $B$, call it
$\mathcal{T}$. Finally, construct a
line through point $n$ (= 1, 2, \dots, 6) which is parallel to
$\mathcal{T}$. The resulting line
intersects the segment from $A$ to $B$ at a point representing the
fraction $n/7$. So $A$ is 0/7
and $B$ is 7/7.\\
\hspace*{9pt}The Greeks were capable of carrying out the
constructions above using only a straight
edge (not a ruler) and a compass.
