A Chiral Polyhedron Made of Kites and Triangles, Along with Its Dual, Made of Triangles and Isosceles Trapezoids
To make this polyhedron using Stella 4d (available here), one starts with the icosahedron, drops the symmetry of the model down from icosahedral to tetrahedral, and then stellates it once. The result is a chiral solid featuring four triangular faces … Continue reading

Polyhedron Featuring Twenty Regular Enneagons, Twelve Regular Pentagons, and Sixty Isosceles Triangles
If the isosceles triangles in this polyhedron were close enough to being equilateral that close inspection would be required to tell the difference, this would be a nearmiss to the Johnson Solids. However, in my opinion, this doesn’t meet that … Continue reading
A CubeBased “Bowtie” Symmetrohedron Featuring Six Regular Hexadecagons, Eight Equilateral Triangles, and Two Dozen Each of Two Types of Icosceles Trapezoid
The two types of trapezoid are shown in blue and green. There are twentyfour blue ones (in eights set of three, surrounding each triangle) and twentyfour green ones (in twelve sets of two, with each set in “bowtie” formation). This … Continue reading
Tessellation Using Regular Triacontakaihexagons, Equiangular Hexagons, Isosceles Triangles, and Isosceles Trapezoids
The equiangular hexagons are very nearly regular, with only tiny deviations — probably not visible here — “from equilateralness.”
Tessellation Using Regular Triacontagons, Isosceles Triangles, Equiangular Triangles, and Isosceles Trapezoids
Little blurbs about posts on this blog get autotweeted on my Twitter, @RobertLovesPi. There’s also an A.I. on Twitter, @Hexagonbot, who retweeted my last two tweets about blogposts here, but will not be retweeting the tweet about this one. Why … Continue reading
