Abstract

Wu's method has been shown to be extremely successful in quickly proving large numbers of geometry theorems. However, it is not generally complete for real geometry and is unable to handle inequality problems. Collins' method is complete for real geometry and is able to handle inequality problems, but is not, at the moment, able to prove some of the more challenging theorems in a practical amount of time and space. This paper presents a combination that is capable of proving theorems beyond the theoretical reach of Wu's method and the (current) practical reach of Collins' method. A proof of Pompeiu's theorem using this combination is given, as well as a list of several other challenging theorems proved using this combination.
