Abstract

It was the purpose of the present study 1) to present the major known theorems concerning the Spieker circle; 2) to show the remarkable analogy between the Spieker circle and the nine point circle; and 3) to extend theorems of the Spieker circle and the definition of the Spierker circle to related configuration that are located outside the given triangle.
