Why Do Shapes Fit Together So Perfectly in a Puzzle?

Imagine playing with building blocks. Each block has special edges that match up perfectly with others, like how a square fits next to another square, and a triangle fits beside another triangle. This is shape fitting! It's like when puzzle pieces know exactly where they need to go because their shapes are made just right for each other.
