In poetry, a rhyme patternor rhyme scheme is defined as the rhyme structure that comes at the end of each line or verse; it is the order that a poet needs to create the poem, unless free verse is being written, where there aren't patterns or metric feet.
In this case, the answer is abab, cdcd, efef, gg since the first line rhymes with the third one while the second one with the fourth one and so on.
