I have this trapezoid in Tikz, and I would like to put some text inside the trapezoid, next to the angles, and also place next to each vertex, outside of the trapezoid, one of the letters A,B,C,D. I have a feeling I need to annotate (0,0) etc. for all of this, but not sure how and how to set the placement. Any ideas?
\begin{tikzpicture}
\newdimen\R
\R=1cm
\newdimen\S
\S=1.5cm
\draw[xshift=10.5\R] (0,0) -- (2.8\S,0)
-- node[rotate=-52]{} (2\S,1.1\S) -- (.8\S,1.1\S)
-- node[rotate=52]{} (0,0);
\draw[xshift=10.5\R] (1.4\S,-.5) node {}
++ (0,-.5) node {};
\end{tikzpicture}
\documentclass{...}
and ending with\end{document}
