Chemical bonding — practice question

The monomer buta-1,3-diene is able to undergo addition polymerisation in more than one way. Two polymers that can be produced are known as cis-poly(buta-1,3-diene) and trans-poly(buta-1,3-diene). Here, cis and trans are used in their normal sense. What is the structure of the repeat unit of cis-poly(buta-1,3-diene)?
