Well, what have you got......?

Explanation:

Now #"cis/trans"# and #"E/Z"# isomers are usually simple to designate with respect to olefins, i.e. #R_1R_2C=CR_3R_4#; with rings they are equally easy, even give the soft exchange between axial and equatorial substituents on a 6-membered ring; trans substituents remain trans whether they are axial or equatorial. Don't despise the use of a model to inform your reasoning; models are not toys, they are tools.
