I need help on this organic chemistry question:

------
What are the number of rotational axes and the number of mirror planes for each of these images? (below)

1,1-dichlorocyclopropane

trans-1,2-dichlorocyclopropane

cis-1,2-dichlorocyclopropane

cis-1-bromo-2,3-dichlorocyclopropane (all cis)

1-bromo-1-chlorocyclopropane

trans-1-bromo-2-chlorocyclopropane

cis-1-bromo-2-chlorocyclopropane

Which of these are superimposable?

Thank you!! :)
