| __SPHERICAL TO PLANAR TRANSFORMATION__ *(Site not responding. Last check: 2007-11-07)* |

| | To illustrate the model, the icosehedral **spherical** triangle and the equilateral planar triangle are each divided into six similar triangles by projecting the three perpendicular bisectors. |

| | To transform a point P on the Icosahedral **spherical** triangle, multiply the distance of the point P from the centroid, (=Dg from Rotation 3, Step 5), by the Amplitude factor and add the Angle factor to the bearing of the point P, (=B"' from Rotation 3, Step 7), from the perpendicular bisector. |

| | This paper explained a scheme using **spherical** coordinate notation to transform the **spherical** facets of a regular icosahedron to planar facets suitable for plotting on an X-Y plotter. |
