WebGeometric isomerism is a type of stereoisomerism where rotation around a bond is restricted, such as in the case of a double bond. Cis and trans isomers are types of geometric isomers, where the functional group is placed differently with regards to the double bond. In general, a cis isomer has molecules on one side of the double bond.
