Blank verse poems are not rhymed, but they are metered in iambic pentameter. Here are some examples of blank verse.
Friends, Romans, countrymen, lend me your ears.
I come to bury Caesar, not to praise him.
The evil that men do lives after them;
The good is oft interred with their bones.
From Julius Caesar by William Shakespeare (Act III, Scene ii)
It little profits that an idle king,
By this still hearth, among these barren crags,
Matched with an aged wife, I mete and dole
Unequal laws unto a savage race,
That hoard, and sleep, and feed, and know not me.
From Ulysses by Alfred Lord Tennyson
Back out of all this now too much for us,
Back in a time made simple by the loss
Of detail, burned, dissolved, and broken off
Like graveyard marble sculpture in the weather,
There is a house that is no more a house
From Directive by Robert Frost
