2. Pattern Blocks - Wikipedia

   en.wikipedia.org/wiki/Pattern_blocks

   Pattern Blocks are a set of mathematical manipulatives developed in the 1960s. The six shapes are both a play resource and a tool for learning in mathematics, which serve to develop spatial reasoning skills that are fundamental to the learning of mathematics. Among other things, they allow children to see how shapes can be composed and ...

3. List of fractals by Hausdorff dimension - Wikipedia

   en.wikipedia.org/wiki/List_of_fractals_by...

   L-Systems branching pattern having 4 new pieces scaled by 1/3. Generating the pattern using statistical instead of exact self-similarity yields the same fractal dimension. Calculated: 1.2683: Julia set z 2 − 1: Julia set of f(z) = z 2 − 1. [9] 1.3057: Apollonian gasket

4. Missing square puzzle - Wikipedia

   The apparent triangles formed from the figures are 13 units wide and 5 units tall, so it appears that the area should be S = ⁠ 13×5 / 2 ⁠ = 32.5 units. However, the blue triangle has a ratio of 5:2 (=2.5), while the red triangle has the ratio 8:3 (≈2.667), so the apparent combined hypotenuse in each figure is actually bent.

5. Wallpaper group - Wikipedia

   en.wikipedia.org/wiki/Wallpaper_group

   A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern. Such patterns occur frequently in architecture and decorative art, especially in textiles, tiles, and wallpaper. The simplest wallpaper group, Group p 1 ...

   A fractal is formed when pulling apart two glue-covered acrylic sheets. High-voltage breakdown within a 4 in (100 mm) block of acrylic glass creates a fractal Lichtenberg figure. Romanesco broccoli, showing self-similar form approximating a natural fractal. Fractal defrosting patterns, polar Mars.

7. Quincunx - Wikipedia

   en.wikipedia.org/wiki/Quincunx

   A quincunx of pips on the five-side of a die. A quincunx (/ ˈkwɪn.kʌŋks / KWIN-kunks) is a geometric pattern consisting of five points arranged in a cross, with four of them forming a square or rectangle and a fifth at its center. [1] The same pattern has other names, including "in saltire" or "in cross" in heraldry (depending on the ...
