Why Does a Pizza Slice Have Curves?

Pizza slices have curves because they’re cut from a round pizza. Imagine you're eating a circle, and someone cuts it like a pie into triangular pieces. But if the slice is curved at the bottom, that’s not just how it looks, it's how it behaves! When you eat straight edges (like a square piece of cake), the sides are flat, but with a pizza, the top stays round while the bottom gets cut, giving it a soft curve. It's like taking a round balloon and cutting off a part, it naturally keeps that curved shape!
