Okay kiddo, listen up! Let's say you have a bunch of shapes with lots of sides, like triangles, squares, and hexagons. We call these shapes "polygons."
Now, imagine you want to cover a certain area with these polygons. Maybe you want to cover a big field with grass, or a wall with paint. But you don't want any gaps or spaces left over - you want everything to be covered perfectly!
This is where polygon covering comes in. To cover the area without any gaps, you need to make sure the polygons fit together perfectly. You might use different shapes and sizes of polygons to make this work.
Think of it like putting together a puzzle. You're trying to fill up a space with a bunch of different pieces, and you need them to fit together perfectly to make the picture complete.
So, to sum up: polygon covering is when you use different shapes of polygons to cover a certain area without leaving any gaps or spaces. It's like putting together a puzzle, but with shapes instead of pictures!
