Final answer:
Blank verse, free verse, and abecedarian are three poetry forms that match the given definitions.
Step-by-step explanation:
Blank Verse: A form that lends itself well to a meditative voice, blank verse is written in iambic pentameter lines that do not rhyme. For example, John Milton's Paradise Lost is written in blank verse.
Free Verse: A poetic form that does not conform to a regular rhythm or set line length. It is often associated with poets like Walt Whitman and does not follow any prescribed rules of form or rhyme scheme.
Abecedarian: A form where the poem works its way through the alphabet, with each line beginning with the letter following the first letter of the previous line. There are no restrictions on meter or rhyme.
