LaTeX bleg


One of my geometry students is LaTeX-ing a writeup of a problem which involves typesetting three points with an arc symbol going over the top of all of them. Neither he nor I could find such a symbol, not even in the Comprehensive LaTeX Symbol List. The closest we came was the \widehat symbol, but that’s not exactly the right thing. Anybody out there know how to typeset this?

    You’ll have to build it yourself — stack a \frown on top of your points.
    Try \stackrel{\textstyle\frown}{ABC}.

  2. If you install the arcs package you will get the \overarc command so that \overarc{ABC}=200^{\circ} looks like this

  4. Or you may try to draw it using tikz/pgf.
