Tessellated roof

So imagine you're playing with blocks, and you have a bunch of triangle-shaped blocks. If you line them up just right, they can fit together perfectly without any gaps or overlaps, kind of like a puzzle. That's what we call a tessellation - it's a pattern made up of repeating shapes that fit together like puzzle pieces.

Now, imagine you have a really big triangular roof to cover a house or a building. Instead of using one big piece of material, we can use smaller triangular pieces that fit together like a puzzle, creating a tessellated roof! These smaller pieces are easier to handle and can be arranged in lots of creative ways to create interesting patterns on the roof.

Plus, if one piece gets damaged, we can just replace that one piece without having to replace the whole roof - kind of like taking one block out of your puzzle and replacing it with a new one. Overall, a tessellated roof is a cool and efficient way to cover a building!
