Theory:

Rhyming words are defined as two or more words that have similar or the same sound at the end. If any two (or more) words rhyme, it means it sounds similar. It may be expressed as a repeating pattern that makes the text sound interesting, musical and pleasing.
For easy understanding, the rhyming words are emphasized.
 
I was angry with my friend;
I told my wrath, my wrath did end.
I was angry with my foe:
I told it not, my wrath did grow.
 
And I water' d it in fears,
Night & morning with my tears:
And I sunned it with smiles,
And with soft deceitful wiles.
 
And it grew both day and night.
Till it bore an apple bright.
And my foe beheld it shine,
And he knew that it was mine.
 
And into my garden stole,
When the night had veiled the pole;
In the morning glad I see;
My foe outstretched beneath the tree.
