Regular triacontagon with given circumcircle. D is the midpoint of AM, DC = DF, and CF, which is the side length of the regular pentagon, is E 25 E 1.Since 1/30 = 1/5 - 1/6, the difference between the arcs subtended by the sides of a regular pentagon and hexagon (E 25 E 1 and E 25 A) is that of the regular triacontagon, AE 1.
Let φ be the golden ratio.The 12 points given by (0, ±1, ±φ) and cyclic permutations of these coordinates are the vertices of a regular icosahedron.Its dual regular dodecahedron, whose edges intersect those of the icosahedron at right angles, has as vertices the 8 points (±1, ±1, ±1) together with the 12 points (0, ±φ, ± 1 / φ ) and cyclic permutations of these coordinates.
Compared with the first animation (with green lines) are in the following two images the two circular arcs (for angles 36° and 24°) rotated 90° counterclockwise shown. They do not use the segment C G ¯ {\displaystyle {\overline {CG}}} , but rather they use segment M G ¯ {\displaystyle {\overline {MG}}} as radius A H ¯ {\displaystyle ...
[C] Coxeter et al., 1954, showed the convex forms as figures 15 through 32; three prismatic forms, figures 33–35; and the nonconvex forms, figures 36–92. [ W ] Wenninger, 1974, has 119 figures: 1–5 for the Platonic solids, 6–18 for the Archimedean solids, 19–66 for stellated forms including the 4 regular nonconvex polyhedra, and ended ...
Only the g10 subgroup has no degrees of freedom but can be seen as directed edges. The highest symmetry irregular decagons are d10 , an isogonal decagon constructed by five mirrors which can alternate long and short edges, and p10 , an isotoxal decagon, constructed with equal edge lengths, but vertices alternating two different internal angles.

Trump, who won the 2024 election but lost the 2020 election to President Joe Biden, has falsely claimed that he lost the 2020 election due to extensive voter fraud, a view shared by millions of ...
