All secants passing through a center of simil-itude of two circles are cut in the same ratio by thecircles. IN PAPER FOLDING n5 232.. If B\, D\, and B2, D<i be the… … Fig. 66. The center of inversion is the center of similitudeof the original circle and its inverse. The original circle, its inverse, and the circle ofinversion are co-axial. 233. The method of inversion is one of the mostimportant in the range of Geometry. It was discov-ered jointly by Doctors…
