I'm not sure how often they'll appear on the final, but cis is basically when you have the same element on the same side of the compound and trans is when they're on opposite sides (e.g. diagonal from each other).
Cis isomers are when two of the same ions are on the same side. This means that there are dipole moments present in the isomer. Trans isomers are when the ions are on opposite sides. So this means that the dipole moments essentially cancel each other out.

The name always includes the prefix "cis" or "trans," as we learned in lecture when it came to naming! I wonder if it's not named, if it's sort of like resonance structure where multiple versions appear, or if it's always assigned.
