Geometry, like arithmetic, requires for its logical development only a
small number of simple, fundamental principles. These fundamental
principles are called the axioms of geometry. The present book is a new
attempt to choose for geometry a simple and complete set of independent
axioms and to deduce from these the most important geometrical theorems
in such a manner as to bring out as clearly as possible the significance
of the different groups of axioms and the scope of the conclusionsto be
derived from the individual axioms.
