This approach is also used in the real world to achieve some of the exotic shapes we now see in modern architecture, such as the curved shape of 30 St Mary's Axe, aka the Gherkin, or the canopy over the courtyard in the British Museum. The method of triangulation is also vital in building our virtual world.
The CGI characters we see in film and on TV are usually approximated by an incredibly fine mesh of triangles, as this makes it easier to digitally store and manipulate them.
Skip to main content. There are a few types of triangle: the equilateral triangle which has 3 sides of equal length, an isosceles triangle with two equal sides, and a scalene triangle which has no sides of equal length. Aside from all the differences in triangles, they have some similarities, they all have three sides and are extremely stable. Comparing how other shapes stand up to pressure proves the triangles resilience. If pressure is applied to one side of a square, it will eventually shift into a rhombus.
No matter the amount of pressure applied to a triangle, it will absorb the pressure and remain rigid. A polygon is a shape made from straight lines, and the triangle is the only polygon that will not shift under pressure. The more compact your structure, the less wax you need to construct the honeycomb.
Wax is expensive. Hexagon Definition: In mathematics and geometry, a Hexagon is defined as a polygon a closed two-dimensional shape with straight sides with 6 sides.
Note that Hexagons have 6 sides and 6 angles. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides…. In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has 8 faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces.
I put together 2 trapezoids to make a hexagon. It has 6 sides and 6 vertices. It has 2 equal parts. My new shape has 2 trapezoids and 4 triangles.

Convex means that any line connecting two points that are part of the polyhedron is also contained in the polyhedron. This means that the five familiar Platonic solids are rigid.
What can be said about non-convex polyhedra? The diagram below shows an icosahedron on the left, a convex polyhedron with twenty faces, contrasted with a solid known as a small stellated dodecahedron on the right. This is not convex as, for example, the lines between two of the pointed vertices are not always contained in the polyhedron.
It has eighteen triangular faces, but later a simpler example was found by Klaus Steffen with only fourteen triangular faces and nine vertices.
