comment Scale Matrix Transform without moving primitive
Makes sense so if I would change my origin from the center to the left hand corner this would help fix the issue right? Makes sense to that, any chance of including that in the answer to make it more applicable?

comment Scale Matrix Transform without moving primitive
Actually It seems to have worked when I only scale 1 axis. This seems to make sense to me for some reason. I changed to glScale2D(1, userData.heightScreen/userData.widthScreen); and because it does not scale the y it does not it does not move. I think your answer still missed my question, how do you scale the y without moving the triangle up.
