The following set of words is an example of true rhyme:
cat and hat.
True rhymes happen when the vowels at the end of the words are identical in pronunciation and the consonants that follow are the same. Plus, the consonants that appear before the ending of the words are different.
cat and hat: the same vowel and consonant at the end ("at") and different consonants at the beginning ("c" and "h").
