Graphics, Figures & Tables ⇒ Tick Marks and base angles

[coachbennett1981]

Localhost gave me this code and I am wondering if two things are possible:

1. Can you draw psarcs to show the base angles are equal. I can't seem to figure this out.

2. Can I put tick marks on the sides that are equal. I have tried used a \ to do this, but it looks terrible.

Any advice would be appreciated...

Code: Select all

\documentclass{minimal}
\usepackage{pstricks-add}

\begin{document}
  \pspolygon(2;90)(2;210)(2;330)
\end{document}
