What does it take for a word to be classified as a "Perfect Rhyme"?

From the link below:

"When the vowels in the final accented syllables of the two rhyming words and the consonants (if any) succeeding the vowel have exactly the same sound, it is called perfect rhyme, e.g., shroud and cloud, mark and bark. "

Note also the wording about masculine and feminine rhymes in the link below.

A perfect rhyme is one in which the two sounds correspond exactly ("by hook or by crook"). In partial rhyme the sounds are similar but not identical:

Then say not Man's imperfect, Heaven in fault;

Say rather, Man's as perfect as he ought....

Whereas a full and stressed rhyme (e.g. hand / stand) or even an unstressed rhyme (such as handing / standing) contain vowels that are common to both words, a half-rhyme like orange / lozenge or silver / salver (technically speaking, pararhymes) has obvious differences between vowels in certain syllables.

I believe that every syllable in each word must rhyme with the corresponding syllable in the other word and the rhythm of the two words must match before you have a "perfect rhyme." There is the possibility of rhyming using approximate rhymes as well. I would define "approximate rhymes" as words whose corresponding syllables do not all match, but whose rhythms are similar and whose final syllables are certainly reminiscent of each other. There is, as a result, a rhyming feel although technically there is no rhyme.

Rhyme in which the final accented vowel and all succeeding consonants or syllables are identical, while the preceding consonants are different, for example, great, late; rider, beside her; dutiful, unbeautiful. Also called full rhyme, true rhyme.

Categories of rhyme include:

tail rhyme: a rhyme in the final syllable(s) of a verse (the most common kind)

masculine: a rhyme in which the stress is on the final syllable of the words. (rhyme, sublime, crime)

feminine: a rhyme in which the stress is on the penultimate (second from last) syllable of the words. (picky, tricky, sticky)

dactylic: a rhyme in which the stress is on the antepenultimate (third from last) syllable (hesitant, president)

triple: a rhyme in which all three syllables of a three-syllable word are stressed equally.

perfect: a rhyme between words that are identical in sound from the point of their first accented syllable forward. (sight and flight, deign and gain and quatrain)

imperfect: a rhyme between a stressed and an unstressed syllable. (den, siren)

identity: a rhyme that starts at a consonant instead of a vowel, or rhyming a word with itself. (gun, begun)

semirhyme: a rhyme with an extra syllable on one word. (bend, ending)

oblique (or slant): a rhyme with an imperfect match in sound.

sight (or eye): a similarity in spelling but not in sound. (cough, bough, or love, move)

consonance: matching consonants. (her, dark)

half rhyme (or sprung rhyme) is consonance on the final consonants of the words involved

assonance: matching vowels. (shake, hate)

A rhyme scheme is the pattern of rhyming lines in a poem.
