负垂足曲线的几何优点
Poristic virtues of a negative pedal curve
摘要：
我们描述了所有的三角形，共享外接圆和踏板圆或外接圆和负踏板圆。这两对都不是poristic;然而，踏板圆的负垂足曲线是一个（非常）特殊的i-圆锥曲线，指向poristic解决方案。随后，其他poristic对出现，舞蹈迅速开始。
英文摘要：
We describe all triangles that shares either circumcircle and pedal circle or circumcircle and negative-pedal circle. Neither of these pairs is poristic; nevertheless, the negative-pedal curve of the pedal-circle is a (very) special i-conic that points toward a poristic solution. Subsequently, other poristic pairs show up and the choreography swiftly begins.
