Notes¶
Let X'Y'Z' be the pedal triangle of the Bevan point, W = X40; then X1319 is the point, other than W, in which the circles AWX’, BWY’, CWZ’ concur. (Floor van Lamoen, Hyacinthos #6321, 6352).
The Helman line is the radical axis of the Zaslavsky pencil, containing the circumcircle and incenter (A. Zaslavsky, August, 2022)
the isogonal image of the Helman line is the I-centered circumellipse having semiaxes of lengths 2R(R-r+d) and 2R(R-r-d), where d = |OI. Accordingly, over Chapple’s porism (with fixed R an r), the I-circumellipse rotates rigidly about its center. (D. Reznik et al., August, 2022). See GeoGebra sketch
Over Chapple’s porism, the locus of each point on the Helman line is a circle, called a Skutin circle, of radius R. (D. Reznik, August, 2022). This is a special case of a result in A. Skutin, “On Rotation of Isogonal Point”, J. Classical Geom., vol 2, 2013.
The set of Skutin circles corresponding to all the points on a given circle in the Zaslavsky pencil all have the same radius. The locus of the center is a circle. (D. Reznik, August, 2022). See GeoGebra sketch
