Why did aristotle believed that oedipus the king was the perfect tragedy?

In Aristotle's Poetics, he outlines the major principles of tragedy, citing Sophocles' Oedipus as the paragon of the form. Aristotle's reasons are clear: to be the perfect tragedy the play must have a perfect plot. Oedipus follows the classic Aristotelian triangle of rising action, climax, and falling action. The play is full of dramatic irony (the audience knows more than the tragic hero) and verbal irony (the use of sarcasm, understatement, and overstatement).

i would just say something like,

i need to go outside owner to pee, hold on owner let me mark this tree. i'm thirsty now "starts drinking water" now i am tired. what are you eating owner can i have some, you can't refuse my cute puppy eyes.

just make sure you write that in your own words that way you don't get in trouble.
