I didn’t read that the Lagrange points were 120 degrees in front of and behind the larger one. I read they were in front of and behind the smaller one.

Yes, that is what the text said. Draw a circle on a piece of paper. Draw points on the circle 120 degrees apart from each other. You should have three points all equidistant. No matter where you put the large body in relation to the smaller body it will be 120 from both Lagrange points.

I have one thing to say to that...

I think the problem with articles like this is the (natural) tendency of lay authors to try to simplify complicated scientific theory in order to make it accesible to the masses. An earlier post noted that the Lagrangian points that are most likely to be inhabited by a third body (ie., a larger planet) are actually 60 degrees (not 120) in front of and behind the smaller body.
