Answer:
meter - the pattern of stressed and unstressed syllables in a poem
iamb - a metrical foot consisting of a stressed and an ustressed syllable
iambic pentameter - five iambs that alternate between stressed and unstressed syllables
pentameter - a line of poetry with five metrical feet
Explanation:
Everything is essentially built from the iambs, which are each one metrical foot with one stressed then one unstressed syllable. Meter is what you call the general arrangement, you could say, of the iambs. The word "pentameter" is built from the word "meter" and the root word "penta" - meter is the measurement in a sonnet, as aforementioned, and "penta" means five. Essentially, meter of five, so five metrical feet. "Iambic pentameter" speaks of iambs, thus it has five iambs, which, as mentioned above, have one stressed then an unstressed syllable.
Hope this helped!
