Maximum number of equilateral triangles in a circle

I am stuck with a question. Given a circle with radius $x$ cm, what is the maximum number of equilateral triangles of side length 1 cm that can fit in the circle without overlapping or overflowing the circle? $x$ is an integer. How do I approach this question?

What are the conditions for a polygon to be tessellated?

Upon one of my mathematical journey’s (clicking through wikipedia), I encountered one of the most beautiful geometrical concept that I have ever encountered in my 16 and a half years on this oblate spheroid that we call a planet. I’m most interested in the tessellation of regular polygons and their 3D counterparts. I’ve noticed that […]

Is a regular tessellation $\{p,q\}$ always possible on some closed surface $S$?

Suppose that we are given positive integers $p$, $q$, $V$, $E$, $F$, a closed surface $S$ and the Euler characteristic $\chi(S)$ of that surface. Suppose that we also know that the following relations hold: $$ qV=2E=pF\\ V-E+F=\chi(S).\tag{$\star$} $$ A regular tessellation $\{p,q\}$ is a tessellation by $p$-gons where $q$ tiles meet in every vertex. Or, […]

Dissecting an equilateral triangle into equilateral triangles of pairwise different sizes

It is know that a square can be dissected into other square such that no two of the squares have the same size. This is the simplest dissection of that kind: Is it also possible to dissect an equilateral triangle into equilateral triangles such that no two of them have the same size?

Floret Tessellation of a Sphere

I’m a programmer looking to create a 3D model of a Floret Tessellation of a sphere, like the one in this picture Class III 8,11 floret planar net (source) If anyone could point me in the right direction for an algorithm to calculate, and ideally group into petals and florets, the vertices, I would be […]

Can someone explain the math behind tessellation?

Tessellation is fascinating to me, and I’ve always been amazed by the drawings of M.C.Escher, particularly interesting to me, is how he would’ve gone about calculating tessellating shapes. In my spare time, I’m playing a lot with a series of patterns which use a hexagonal grid, and a tessellating design I saw on a chair […]

Nets of Geodesic spheres

I would realize the papercraft of a geodesic sphere like this: It is the dual of the one discussed in THIS OTHER QUESTION . Where can I find the printable nets, or the online resources to create them? In the other discussion I learned that there are 3 classes of possible tessellations. One of these […]

Are the vertices of a Voronoi diagram obtained from a Sierpinski attractor also a kind of attractor?

Trying to understand how the Voronoi Diagrams work I did a test generating the Voronoi diagram of the points obtained from The Chaos Game algorithm when it is applied to a $3$-gon. The result is a set of points part of the Sierpinski attractor, the Voronoi cells and the vertices of each cell. This is […]

doubly periodic functions as tessellations (other than parallelograms)

I think of a snapshot of a single period of a doubly periodic function as one parallelogram-shaped tile in a tessellation. Could a function have a period that repeats like a honeycomb or some other not rectangular tessellation?

Why a tesselation of the plane by a convex polygon of 7 or more sides is not possible?

I read in several places, including Wikipedia, that a tessellation of the plane by a single, convex, $n-$sided polygon is not possible for $n\geq7$. I was not able to locate a proof, or a paper that discusses this. Maybe it is too trivial, but I am not able to figure it out myself. So I […]
