Hydrogenation of alkenes

How many structural isomeric alkenes ($\ce{C_6H_{10}}$) can be hydrogenated to give methylcyclopentane? Would there be three? I drew out what I thought was correct but I just want to confirm that there are three.

There are 4 structural isomeric alkenes ($\ce{C_6H_{10}}$) that can be hydrogenated to give methylcyclopentane.
