Which type of poetry contains 3 quadrants and a couplet?

The Shakespearean sonnet, also called the English or Elizabethan sonnet, consists of three quatrains and a final couplet. The quatrains rhyme ABAB, CDCD and EFEF, and the final couplet rhymes GG. The couplet variously summarizes the reflections in the quatrains, delivers an ironic twist at the end or looks at the same topic as the quatrains from a new perspective.
