Because it's always right!
"Right" pulls off a clean double meaning: a right angle is literally called a "right angle," and being "always right" means never being wrong. The joke works especially well because right angles genuinely are a fixed, definitive thing in geometry — they can't be disputed.
Deliver the punchline with confident finality, like you've just proven your point beyond all possible objection.
