Uniform tilings in hyperbolic plane

A tiling in the hyperbolic plane is like a puzzle where all the pieces are the same shape but fit together perfectly. It's like making a jigsaw puzzle using only one kind of piece. In the hyperbolic plane, these pieces are usually triangles, and when you put them together, they create a beautiful and intricate pattern. It's like drawing a picture in a special way that looks really cool and special.
