By definition of cis and trans isomerism , the substituent groups when oriented in the same direction constitute the cis isomer and when oriented in the opposite direction constitute the trans isomer.

The isomers are visualized in chemistry by Wedge-dash notation . The cis isomer is represented by showing both the substituent groups with wedge (coming towards you from the plane of the screen) and the trans isomer is represented by showing one substituent with a wedge and another with dash (going away from you from the plane of the screen )
