What is a rhyme scheme and how do you use it?

This term is usually often used when referring to poetry and pretty much means that lines will rhyme in a specific order. For example line every two lines will rhyme with each other.

Example:

The dog ran

Into the garbage can

The cat said meow

While the dog said 'ow'

A Rhyme Scheme refers to the particular lines in a piece of poetry that rhyme, usually by using words at the end of each line that sound similar.
