[OS X TeX] Left Justified Symbol

[Rose Charlie]

This is a LaTeX question; not a TexShop question. I hope that's Ok. I  
can't find an answer anywhere I look.

I'd like to put a  \blacktriangleright  symbol, left justified, on the  
SAME LINE as an equation which contains a definition as a way for the  
reader to spot definitions quickly while skimming through the  
document. Can anyone help?
