# Change item symbol within itemize in beamer

I'm using beamer to create a presentation and I'd like to mix item shapes. Namely, I'd like to use something like

\begin{itemize}
\item[\circle] Something
\item[\triangle] A conclusion
\end{itemize}


What's the name of the triangle shape used as a beamer template?

@touhami Identifying symbols per se is not really the issue. – Alan Munn Feb 14 at 18:43
@AlanMunn I understand the question in this way, now I am not sure :-) – touhami Feb 14 at 18:46

\documentclass{beamer}
\useinnertheme{circles}
\newenvironment{trienv}{\only{\setbeamertemplate{items}[triangle]}}{}
\newenvironment{squareenv}{\only{\setbeamertemplate{items}[square]}}{}
\begin{document}

\begin{frame}
\frametitle{Some bullet shapes}
\begin{itemize}
\item<tri@1-> A triangle item
\item<square@1-> A square item
\item A circle  item
\end{itemize}
\end{frame}

\end{document}
