Mass production of Theorems of Elementary Geometry and its Application

In our previous research, we got the computer program of the mass production of the theorems of the elementry geometry. The several inference rules, of Gentzen's logical calculus system LK were used in the program. To product the useful theorems, we need many geometrical axioms. In the mathematical textbooks of junior high school, about twenty geometrical axioms appear. But many other propositions used indirectly to prove the geometrical problems. The purpose of this research is to find those propositions and use them as the geometrical axioms. At first, we searched them in the talking and the solutions to the geometrical problems in the school lessons. Secondly, we searched them in the old textbooks whose descriptions of the geometrical proofs were precise. And we got over fifty geometrical axioms. Using these axioms, we can get the useful theorems of elementary geometry.
