When Aaliyah’s father saw her applying nail polish instead of doing her math homework, he said, “You look like you’re working very hard. I’m sure you’ll do great on your test tomorrow.”

Which type of irony is being used here? How do you know?

The irony being used here is verbal irony because the father is saying one thing ("I'm sure you'll do great on your test tomorrow") but meaning the opposite (he knows Aaliyah is not studying and is not likely to do well on her test). This is evident because the father's statement is clearly sarcastic and meant to criticize Aaliyah's lack of effort in studying for her test.
