The icosahedron has three special orthogonal projections, centered on a face, an edge and a vertex:
| Centered by | Face | Edge | Vertex |
|---|---|---|---|
| Coxeter plane | A2 | A3 | H3 |
| Graph | |||
| Projective symmetry |

| Graph | Face normal |
Edge normal |
Vertex normal |

Famous quotes containing the word projections:
“Western man represents himself, on the political or psychological stage, in a spectacular world-theater. Our personality is innately cinematic, light-charged projections flickering on the screen of Western consciousness.”
