Is there a reflex angle symbol?

Question

I only knew this angle symbol "$\angle$", which is usually used to represent acute angles. But now I have accounted a problem, where I wanted to represent the reflex symbol of $\angle ABC$.

I know, I can simply say "The reflex $\angle$ of $\angle ABC$" or "2$\pi$ - $\angle ABC$", but is there a symbol for reflex angle, just for interest?

Answer 1

If allowed to handwrite (or in this case to use a drawing software), I would use something similar to $\large ABC$. Not sure if this is standard notation or if there is some $\LaTeX$ glyph for that.

The point is that you can invent the symbol you want and use it consistently... the only two matters are

1. Is it clear? In case of doubt define it and problem solved.
2. Can I typeset it? In this case there are always workarounds.
