How do parallel lines meet at infinity in perspective?

Question

I remember my art teacher saying that parallel railway tracks meet at the horizon, but my math teacher said parallel lines never meet. Which one is right? Is there a mathematical framework where parallel lines actually do intersect?

Great question! The reasoning comes from looking at patterns in exponents and understanding that math is consistent across all operations.

This is one of those things where the simple version you learn in school hides a much deeper mathematical truth underneath.
