Here's what I get.

Explanation:

The first isomer has two chlorine atoms on the same carbon,

The π-bond in alkenes prevents rotation about the #"C-C"# axis.

Thus, thee are two isomers with the chlorine atoms on different carbons:

  • one has the two chlorine atoms on the same side of the double bond
  • the other has the two chlorine atoms on opposite sides of the double bond
