Plane geometry

2001
Abstract We shall assume that the set of real numbers, ℝ, is a familiar object on which we can perform the usual arithmetic operations.

Groups and Plane Geometry

Studia Logica, 2005
In the precisely written paper the author shows that the first-order theory of a large class of plane geometries and the first-order theory of their groups of motions, understood both as groups with a unary predicate singling out line-reflections and as groups acting on sets, are mutually interpretable.

Absolute Plane Geometry

1981
In this chapter we will review the basic properties of Absolute Plane geometry, based on the Birkhoff axioms. All the theorems to be considered are also theorems of Euclidean geometry and hence, for the most part, will be familiar to the reader.

Further Plane Geometry

1979
The modern approach to geometry places emphasis on symmetry and transformations of the Euclidean plane. Traditional geometry consists of a few basic axioms and a series of theorems, each of which is proved by reference to those earlier in the series. In this chapter a formal statement is made of some important theorems, with examples to show how they ...
