Words that genuinely rhyme with incidence (matching stressed vowel /ɪ/ and following /nsɪdəns/): coincidence. Other -ence words such as evidence, residence, and confidence differ in their stressed vowel and are not rhymes. The word incident shares the initial 'incid-' but ends with -ent (/-ənt/), so it sounds different.
