@Viridian: I actually misstated a little. I don't have an Acromat. I have a Funk Acroplat Platter. The only mat I have for the glass platter is the ringmat. The original mat is gone.
@Slanski62 and Viridian: Thank you for the information on where to get a protractor.
@Goatwuss: You say the acrylic platters are designed to be used without a mat. How about the Acroplat Platter?
It looks like I have several options:
Glass with Ringmat
Acroplat Platter alone
Acrylic Platter alone
Does it make sense to also try the Acroplat Platter and the Acrylic platter with the Ringmat?
Finally, what exactly am I listening for when I try these different platters? Is the difference going to be obvious with casual listening or is this a difference I'm only going to pick up when listening to the same track of music on the different platters consecutively while sitting in the sweet spot at the ideal volume level and my ears freshly cleaned out?
