In this picture you see that when you break the double bond the Br isn't anti. Why is that ?

Hey, Irene!

The bromines are actually anti in both problems! Notice that if you rotate the molecule to look like a cis double bond, the bromines have opposite wedge/dash information. Rotation across an axis will reverse the wedge/dash information. I'd recommend using models to see how this actually works :) Let me know if you have any other questions!
