论文摘要
四边形的对角线形成四个组件三角形（以两种方式）。对于各种形状的四边形，我们检查了位于这四个组件三角形中的1000个三角形中心。使用计算机，我们确定四个中心何时形成特殊的四边形，例如菱形或环状四边形。典型的结果是以下内容。等距四边形的对角线将四边形分为四个非重叠三角形。然后，这四个三角形的Nagel点形成了正统的四边形。
The diagonals of a quadrilateral form four component triangles (in two ways). For each of various shaped quadrilaterals, we examine 1000 triangle centers located in these four component triangles. Using a computer, we determine when the four centers form a special quadrilateral, such as a rhombus or a cyclic quadrilateral. A typical result is the following. The diagonals of an equidiagonal quadrilateral divide the quadrilateral into four nonoverlapping triangles. Then the Nagel points of these four triangles form an orthodiagonal quadrilateral.
