What do you call a poem consisting of 13 or 10 lines with two rhymes?

There's no specific name for a poem with 13 or 10 lines and two rhymes. Here's why:

* Line Count: Poetry is often categorized by structure, but line count alone isn't a defining factor. Poems can have any number of lines.

* Rhyme Scheme: Two rhymes could mean a wide variety of rhyme schemes, like AABB, ABAB, or something more complex.

* Form: The rhyme scheme and line count need to be part of a recognized form (like a sonnet, villanelle, or haiku) to have a specific name.

Examples:

* Sonnet: A 14-line poem with a specific rhyme scheme and structure.

* Limerick: A 5-line poem with a specific AABBA rhyme scheme.

* Haiku: A 3-line poem with a 5-7-5 syllable structure, typically unrhymed.

So, without a specific rhyme scheme or other structural elements, a 13- or 10-line poem with two rhymes would simply be called a poem.
