Can a formula of #C_5H_10# generate geometric isomerism?

My word....but it is an isomer of #C_5H_10#...

Explanation:

#C_5H_10# specifies #"the one degree of unsaturation..."#, which specifies an olefinic bond or a ring junction. I think there are FIVE cyclic isomers with this formula: #"cyclopentane,"# #"methylcyclobutane, ethylcyclopropane,"# #"1,1-dimethylcyclopropane, and 1,2-dimethylcyclopropane."#

And #"1,2-dimethylcyclopropane"# can give rise to TWO geometric isomers, which are?
