I can see from the visual of the sets that D_{1} ∩ D_{2} is not connected, but I'm not sure how to prove this. I figure we would start by assuming the set is connected and there exists a polygonal curve in the set between some two points and then trying to derive a contradiction, but I don't know how to show the contradiction in this case.

Simple observation is enough
