Re: Help: about positioning TikZ picture

I think the problem is that the bounding box changes for each frame.
Try this instead:
\documentclass{beamer}
\usepackage{tikz}
\begin{document}
\frame[plain]{
\begin{figure}
\begin{tikzpicture}
\useasboundingbox (-2,1) rectangle (3,-1);
\only<1-2>{
\draw (-1,0) -- +(3.5,0);
\draw (1,0) ++(210:2cm) -- +(30:4cm);
\draw (1,0) +(0:1cm) arc (0:30:1cm);
\draw (1,0) +(180:1cm) arc (180:210:1cm);
\path (1,0) ++(15:.75cm) node{$\alpha$};
\path (1,0) ++(15:-.75cm) node{$\beta$};
\draw[red] (0,0) circle (2pt) node[anchor=south, color=red]
{$(0,0)$}; %
}
\only<2-3>{
\path (1,0) ++(15:-2.75cm) node{$\gamma$}; }
\end{tikzpicture}
\end{figure}
}
\end{document}
The above example works as intended. Try to experiment with the bounding box:
\useasboundingbox (-2,1) rectangle (3,-1);
You could for instance use
\useasboundingbox (0,0) rectangle (0.5,0.5);
to get a different placement.
