### Geometry/Chapter 1

Section 1.3 - Undefined Terms: removed - (again, more later) - not needed

-79

### Geometry/Chapter 1

Exercises: getting my premises and predicates mixed up - corrected

-22

### Geometry/Chapter 1

Exercises: added that these logic questions are based on the major/minor premise form and that the subject of the premise must be part of the affirmative or negative answer - otherwise the exercises are difficult

### Geometry/Chapter 1

Section 1.2 - Reasoning: removed link to Wikipedia article - not needed - the following material deals with the matter

### Geometry/Chapter 1

Section 1.1 - Introduction: removed sentenceː "Although this textbook is not a re-interpretation of ''The Elements'', it will include more than just facts about geometric objects..." - Reasonː not needed - the introduction is fine

Section 1.1 - Introduction

### Geometry/Chapter 1

Section 1.1 - Introduction: removedː (or elementary) - not so much elementary because it involves abstract concepts such as ratio, equality, boundary - e.g. for equalityː if A is equal to C and B is equal to C than B is equal to A

-68

### Geometry/Chapter 1

no edit summary

m-114

### Geometry/Chapter 1

Inductive Reasoning: removedː "Looking at the example above you may" - not needed - the previous editors shows clearly why squaring a half results in a quarter

-63

### Geometry/Chapter 1

Inductive Reasoning

m-2

### Geometry/Chapter 1

Inductive Reasoning: changedː "Based on observations, this appears to be true." to "Based on the result of squaring whole numbers this appears to be true." - it doesn't matter if its negative or positive - it is still a whole number

+23

### Geometry/Chapter 1

Inductive Reasoning: "A beginning observer of American baseball may conclude" - changed "beginning" to "foreign" - that is nearer to no knowledge of the game

-2

### Geometry/Chapter 1

Inductive Reasoning: this paragraph ends with Kuhn - but he is not mentioned so I added his name and the concepts of "paradigm" and "generalizations" - the importance of this is not lost on those who have read the "Almagest" by Ptolemy

+201

### Geometry/Chapter 1

Section 1.1 - Introduction: typo and removed link to Nasa

-68

### Geometry/Chapter 1

Section 1.3 - Undefined Terms: adding that Hume considered all knowledge "a posteriori" which I've just discovered gave Einstein the reason to abandon the axioms of Euclidean geometry to invent a curved time-space theory- oh well learn something new

+27

### Geometry/Chapter 1

Section 1.3 - Undefined Terms: removed bold - not needed and looks better - bold is useful but the terms were "segment", "ray", and "angle" which I think most people would know

-69

## 23 August 2016

### Geometry/Chapter 1

Section 1.3 - Undefined Terms: changed word to "understanding" - I'm a bit puzzled why this whole section is called "Undefined Terms" - they are either a priori or a posteriori but all things are defined - it should be "Postulates or Common Notions"

+2

### Geometry/Chapter 1

Section 1.3 - Undefined Terms: adding Hume and his work On Human Nature - basically the questioning of axioms was a youthful Hume - the point he was illustrating was that the study of human nature may be approached from science

+151

### Geometry/Chapter 1

Deductive Reasoning: adding "that are not parallel will intersect" to "it can be used to deduce that two different lines intersect in at most one point." - in the sense of extended without limit

+24

### Geometry/Chapter 1

Section 1.2 - Reasoning: Chicago Manual of Styleː spell non-technical numerals below one-hundred

m+6

### Geometry/Chapter 1

Section 1.2 - Reasoning: removed Wikipedia link to Baseball article - keep focus on geometry

-25

### Geometry/Chapter 1

Section 1.1 - Introduction: tightened sentence - no need for the demonstrative pronoun "that" - I'm not sure if it is "his method" - many of the proofs were common knowledge - I thought he was the first to order them

-18

### Geometry/Chapter 1

Section 1.1 - Introduction: no need for speech marks - no emphasis needed

m-2

### Geometry/Chapter 1

Section 1.1 - Introduction: rewrote "In the book, Euclid started with some basic concepts. He built upon those concepts..." - "In this book Euclid provides methods using just a compass, ruler and a protractor to prove geometrical statements."

-2

### Geometry/Chapter 1

Section 1.1 - Introduction: removed speech marks from "proof" - not needed

-4

### Geometry/Chapter 1

Section 1.1 - Introduction: removing Wikipedia links - same reason as before

-29

### Geometry/Chapter 1

Section 1.1 - Introduction: Removed speech marks on the first word of a paragraph - not needed - also there is no need to link to the Wikipedia article - this book can go way beyond an article

-25

### Geometry/Chapter 1

Section 1.1 - Introduction: removed brackets - not needed - the sentence is fine - shouldn't how Eratosthenes measured the Earth be included - wasn't it quite a distance between the well and the other point

-2

### Geometry/Chapter 1

Section 1.4 - Axioms/Postulates: rewrite - the paragraph "Undefined Terms" is very abstract - wouldn't it be better to go straight to the Axioms
