??? Oh yeah, says who?
protein / poutine
p[]oh teen / poo teen => both start with a p, then there's an oh or oo (which are similar) and both end the same way – disyllabic rhyme
cactus / practice ?
[]ah ck təss / []ah ck tiss => ignoring the first consonant (cluster) which anchors the rhyme and pronouncing the u as a schwa (which it is), the ck's are the same and təss and tiss are totes similar – disyllabic rhyme
skeleton / gelatin ?
trisyllabic goodness – again, the way we pronounce the on in first word is not like the on in frond but like the ən in motion (UHn) and the way we pronounce the at in the second word is not like the at in bat or cat but like the ət in … hmm, none spring to mind but it's an UHt sound here if you listen to it – sgɛ́lɪtən or ˈskelɪtən – ˈʤelətɪn – so you've k vying with g (both hard), e with e, l with l, ɪ with ə (close sounding!), t with t, ə with ɪ (close sounding!), n with n
