A couplet is a two-line stanza; if the two lines rhyme it is called a rhyming couplet. A tercet or triplet is a three-line stanza. A quatrain is a four-line stanza. Sometimes a stanza is called a verse or a stroph. The meaning is essentially the same, but stanza is the far more popular term. The important thing to remember is that, except when you are using a set form, you have a great deal of leeway in how you use stanzas.
