Poetry is not confined to any sort of convention, however, there are many a way to transmit a message or a concept through a specific modality by making use of rhyme, meter among other poetic elements. In the case of the poem "Polar Opposites", a defined structure and/or style is not present. Ideas of constant opposition and contradiction can be perceived without a strict use of a poetic convention. For this reason it can be considered a free verse poem.
