I say that this molecule is not aromatic because both its A and B carbons are sp³. In order for the molecule to be aromatic it cannot have sp³ carbons because it must be planar. However i am not 100 % sure about this molecule's aromaticity.

Also, i'm trying to determine which protons are chemically equivalent on this molecule for its H NMR signal. I tried to determine this by using a horizontal plane to cut the molecule in half right between the A and B carbons.
However, the wedges confuse me about this.

Re equivalences, what happens when you flip the system end over end, going towards you?
