A character says one thing but means the opposite = verbal irony
A character expects one thing to occur, but something else happens = situational irony
The audience knows something a character does not = dramatic irony
Explanation:
The first one is obvious because verbal is another word for speaking, the second one is generally based on the situation, and the third one is based on the rising of drama in the story. I'm not sure if you'll understand this explaination, I'm a theater kid.
