Numbers inside triangles

Question

I found a good answer here about how to insert characters into circles, but how could one place a triangular order around a character? Would it involve $\triangle$?

Answer 1

Modified Stefan Kottwitz answer on question:

\documentclass{article}
\usepackage{tikz}
\usepgflibrary{shapes}
\newcommand*\triangled[1]{\tikz[baseline=(char.base)]{
            \node[regular polygon, regular polygon sides=3,draw,inner sep=1pt] (char) {#1};}}
\begin{document}
Numbers aligned with the text:  \triangled{1} \triangled{2} \triangled{3} etc.
\end{document}
