These words all rhyme with 'refine' (riˈfaɪn): they share the stressed vowel /aɪ/ and ending /n/. Note that 'define', 'confine', and 'fine' also share the '-fine' spelling, while 'line', 'mine', and 'shine' are spelled with '-ine' but sound the same. Be careful not to confuse these with words like 'examine' or 'engine' that have different vowel sounds.
