Draw triangle with text in vertices/edges

I'm trying to reproduce the following:



enter image description here



I tried to use tikzpicture and made something "by hand" (even knowing that that wasn't the better way), but I was not able to find a way to have the exactly result, especially in the middle of the text as the image above. My code:



documentclass{article}
usepackage{tikz-qtree}

begin{document}
begin{tikzpicture}
Tree [.A edge[roof]; {$alpha_{1} ldots alpha_{n}$} ]
end{tikzpicture}
end{enumerate}
end{document}
