Haga's theorems in paper folding and related theorems in Wasan geometry Part 2
arXiv:1802.03078
Abstract
We generalize problems in Wasan geometry which involve no folded figures but are related to Haga's fold in origami. Using the tangent circles appeared in those problems we give a parametric representation of the generalized Haga's fold given in the first part of this two-part paper.
