The diagram below shows how this can be used on a pentagon (a five-sided polygon). Interior angles of a pentagon My own image The Interior Angle Sum of Further Polygons We can see in the pentagon diagram that a pentagon is split into three internal triangles, so it must have an interio...
This means that once a Delaunay triangulation has been computed for a set of points, a Voronoi diagram can be drawn without any additional data - just draw lines connecting the centers of the circumcircles! Voronoi diagrams are very useful for efficiently and organically partitioning (splitting up...
Turn a circle into a square. The duplication of the cube. The Regular Heptadecagon. (regular N polygon). At that time, it had the origin point and all the points with unit distance. In fact it is a case of how function corresponds to what it is. (Finite and Infinite.). Function ...
day-glo colors are especially bright, clean materials which can be much brighter than conventional colors. They were first developed in the 1930s, finding their way into magic shows, stage shows, and movie promotion posters. They contain certain dyes and resins that produce colors far brighter ...
DHQ-graphene, a recently discovered two-dimensional carbon allotrope characterized by a unique arrangement of decagonal, hexagonal, and quadrilateral carbon rings, has garnered attention. So far, DHQ-BN’s structural, mechanical, electronic, and optical properties remain untested. DHQ-graphene is a ...
Ptolemy began his discourse by calculating the chord lengths for the central angles corresponding to the sides of a regular inscribed decagon, hexagon, pentagon, square, and triangle. He determined the first three of these chords using the figure below with the following proof3....
In other words, if you extend the channel line from an adjacent star, a line that really is at 30° to the horizontal, it would come in a bit high for the vertex X in the diagram above: 3.5 mm high in a pattern where s, the side length, is 100 cm. Although I was pretty picky...
Voronoi diagram on Wikipedia Fibonacci sequence Related to Golden ratio Sequence of numbers in which each number is the sum of it's two preceding numbers. Binet's formula shows that the ratio of two consecutive numbers tends towards the golden ratio as the sequence progresses. Fibonacci numbers ...

We then changed the arrangement of pillars. The pillars on the micropatterned surface were arranged into three kinds of cells, regular dodecagonal, hexagonal and square cells (Fig. 3a–d) with equal pillar intervals. We found that this designed substrate evolved the 2D foams into discrete dodec...
