In geometry, the rectified truncated icosa … In geometry, the rectified truncated icosahedron is a convex polyhedron. It has 92 faces: 60 isosceles triangles, 12 regular pentagons, and 20 regular hexagons. It is constructed as a rectified, truncated icosahedron, rectification truncating vertices down to mid-edges. As a near-miss Johnson solid, under icosahedral symmetry, the pentagons are always regular, although the hexagons, while having equal edge lengths, do not have the same edge lengths with the pentagons, having slightly different but alternating angles, causing the triangles to be isosceles instead. The shape is a symmetrohedron with notation I(1,2,*,[2]) symmetrohedron with notation I(1,2,*,[2])
, 截半截角二十面體是一種凸多面體，屬於環帶多面體，其對偶多面體為菱形九十面體。有92個面，其中有12個正五邊形、20個等邊六邊形和60個等腰三角形組成。在截半截角二十面體92個面中，只有12個正多邊形。 截半截角二十面體是由截角二十面體截去頂點所構成，雖然它看似半正多面體，但並不是，因為它只有五邊形是正多邊形，三角形和六邊形皆非正多邊形，由於該多面體由正多邊形與非常接近正多邊形的對稱等邊多邊形組成，因此，此多面體又可以被歸類為擬詹森多面體。
