Chapter 4
Proofs in Incidence Geometry
In this chapter, we will begin to discuss the process of constructing rigorous mathematical proofs. First, we discuss the general structure of proofs and describe some
“templates” for proofs of different types. Havin
Chapter 3
The Language of Mathematics
In the previous chapter, we introduced incidence geometry, and discussed three of its
four elements as an axiomatic system: undeﬁned terms, axioms, and deﬁnitions. We
have not yet introduced the fourth and most import
Chapter 2
Incidence Geometry
Motivated by the advances described in the previous chapter, mathematicians since
the early twentieth century have always proved theorems using what is now called
the axiomatic method. The purpose of this chapter is to describ

Reading Euclid
The story of axiomatic geometry begins with Euclid, the most famous mathematician in history. We know very little about Euclid’s life, save that he was a Greek who
lived and worked in Alexandria, Egypt around 300 B . C . E . His m

Conventions for Writing Proofs
Writing mathematical proofs is, in many ways, unlike any other kind of writing.
Over the years, the mathematical community has agreed upon a number of moreor-less standard conventions for proof writing. This appen

Properties of the Real Numbers
Because our axioms for plane geometry are predicated on an understanding of the
real number system, it is important to establish clearly what properties of the real
numbers we are taking for granted. In this appen
Appendix B
Birkhoff’s Axioms for Plane Geometry
These axioms are taken from the 1932 article A set of postulates for plane geometry, based on scale and protractor, by George D. Birkhoff [GDB32]. In Birkhoff’s
system, the undeﬁned terms are point, line, di
Appendix A
Hilbert’s Axioms for Plane Geometry
These axioms are taken from The Foundations of Geometry by David Hilbert (1899),
as translated by E. J. Townsend in 1902 [DH02]. Although Hilbert’s treatment includes axioms for three-dimensional spatial geom
