It only happens around a c=c as there is no free rotation about the double bond. You need to have 2 of the same atoms/molecules on either side of that double bond. When they are both at the top or both at the bottom it is cis. When they are diagonally accross from each other it is trans. Hope this helps.... sorry if it doesnt make sense it is quite hard to discribe in words

cis
those are defined by position of double bonds, the possible one,s are cis-cis,cis-trans,trans-trans.
Cis molecules have the properties of all substances but of course the values are different for cis and trans.
Cis and trans are configuration.
According to studies, Cis and Trans potassium dioxalatodiaquachromat differ by the trans potassium form being less soluble than that of Cis, therefore it differs in chemistry relating to the absorption spectrum.

Georg Peter Maria Seeber has written: 'Coordination chemistry of cis, trans-1,2,5-Triaminocyclohexane'
The geometrical isomerism is mainly Cis-trans isomerism but in some cases we use another term Z and E isomers, they are almost same.
Because the molecular energy is higher in the 13-cis than 7 & 11-cis.
