enThe Japanese Theorem for Nonconvex Polygons

<div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><strong>Abstract</strong>. The so-called "Japanese theorem" dates back over 200 years; in its original form it states that given a quadrilateral inscribed in a circle, the sum of the inradii of the two triangles formed by the addition of a diagonal does not depend on the choice of diagonal. Later it was shown that this invariance holds for any cyclic polygon that is triangulated by diagonals. In this article we examine this theorem closely, discuss some of its consequences, and generalize it further.</p></div></div></div>A Political Redistricting Tool for the Rest of Us

Individual states are responsible for redrawing their congressional districts. Often sophisticated (and expensive) software packages are used to guide redistricting committees when drawing the new boundaries. Much of the cost is due to the fact that redistricting is a fantastically complicated problem. We do not propose to give a definitive way of building political districts.</p></div></div></div>Rethinking Pythagoras
