It's sometimes used to indicate 0V, or sometimes the -ve supply rail
(if you've got +ve and -ve rails).  I'm sure there must be a standard
for its use.

If there's no labelling on the triangle, then that's really slack of the
person who drew the circuit, and I guess you'll just have to work it
out from the context!

Good luck,
