Triangles mean major 7, yes. I didn't know what they meant - I'd never even seen that notation - until my high school jazz band director used them, and now I guess it's become a North American jazz education standard. Thank you Jamey Abersold.
I prefer geometrical objects 
to notate major 7 instead of just "C", because to me "C" means C major triad, no extensions. The clearest way is to write maj7.
