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 describ
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
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 axio

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

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-

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 th
