Special cases are right triangles (p q 2). Uniform solutions are constructed by a single generator point with 7 positions within the fundamental triangle, the 3 corners, along the 3 edges, and the triangle interior. All vertices exist at the generator, or a reflected copy of it. Edges exist between a generator point and its image across a mirror.
Because the internal angle of the equilateral triangle is 60 degrees, six triangles at a point occupy a full 360 degrees. The triangular tiling has Schläfli symbol of {3,6}. English mathematician John Conway called it a deltille , named from the triangular shape of the Greek letter delta (Δ).
Broken down, 3 6; 3 6 (both of different transitivity class), or (3 6) 2, tells us that there are 2 vertices (denoted by the superscript 2), each with 6 equilateral 3-sided polygons (triangles). With a final vertex 3 4.6, 4 more contiguous equilateral triangles and a single regular hexagon.
The common fold normally involves creating a triangle or "V" shape out of the first available sheet or square on a toilet paper roll. Commonly, the two corners of that sheet are tucked behind the paper symmetrically, forming a point at the end of the roll. More elaborate folding results in shapes like fans, sailboats, and even flowers.
The modified Schläfli symbol for a right triangle domain: (p q 2) → {p, q}. The Coxeter-Dynkin diagram is a triangular graph with p , q , r labeled on the edges. If r = 2, then the graph is linear, since diagram nodes with connectivity 2 are not connected to each other by a diagram branch (since domain mirrors meeting at 90 degrees generate ...
Imagine crescent rolls arranged in a sunburst pattern, topped with seasoned ground beef mixture, then wrapped up and baked to golden perfection. It’s basically a giant pull-apart taco.
