The form occurs when hydrogens on both carbons forming the double bond lie on opposite sides of the bond.

The trans isomer of the Alkene

Explanation: Alkene have the ability to form geometric isomers when the Hydrogen are at the opposite direction of the carbon it leads to a Trans Alkene but when they are at the adjacent it is called a Cis Alkene
