Answer:Rhymes are used in all types of poetry, but they don't always occur in regular patters or at the ends of lines—so not all poems that use rhyme necessarily have rhyme schemes. Rhyme schemes are only used to describe poems that use end rhyme (that is, rhymes at the ends of lines).
Step-by-step explanation:
Rhyme scheme is a poet's deliberate pattern of lines that rhyme with other lines in a poem or a stanza. The rhyme scheme, or pattern, can be identified by giving end words that rhyme with each other the same letter.
