Reading For the first few lectures. 
<br>
This class-to reading matchup is a bit inexact:
  meaning, for example,  that  some of  the reading for class 2 might be <br>
more timely and useful    to class 3 or inversely some of class 3's reading might be more useful in class 2.  
<br>
<br>
Class 1:
<br>
Pillars:  Ch 1: p. 1-10. Ch 2:  sections 2.1, 2.2, and 2.7.
<br>
Note: Sec. 2.7 contains  what I called `Thales' Theorems, I and 2' in class
the 1st day.   Stillwell calls another theorem - see his sec. 2.6--
``Thales'  Theorem  ' " 
<br>
  Euclid:  Book 1:  Thru to parallel postulate usage (I.29, 30, 31).  Then skip to
what I call  ``Thales''" : III.20, 31.
<br><br>

Class 2 [Sept 30] :   [Postulates. Parallel Postulates. Angles sum to 180. Construction of various angles.
Inscribing and circumscribing N-gons, N=3, 4, 6, 8]  
<br>
Pillars: p. 4, 5.  Sec 2.1, 2.2    section 2.2; rest of ch. 2.  
<br>
Euclid:  Read the postulates for sure.  Some common notions.
Then I.1-I.33 or 34.  Esp. I.29- I.32.  All of book IV except the Pentagon propositions.
<br><br>
Class 3 [Oct 2] .  [ AREA.  SCALING. SIMILARITY]<br>
Pillars: p. 5 and 6.  Ch. 2: 2.3, .4, .5 Maybe 2.6 . Pythagoras. 2.5, 2.7.
<br>
Euclid: I.35-I. 49.  Esp. I.48, I.49.  What does Euclid mean by ``equal'' in I.35?


<br><br>  Weeks of Oct 7-18. After these readings
we   have   the material needed for   midterm.  

<br>
Euclid:  IV.2-.5: inscribing and circumscribing triangles,  circles.

IV.10-13: pentagons.

IV.14-15: hexagons.

<br>
[Potential HW: Make sense of the construction of  IV.16 for  a regular 15-gon. Why does it work?]
 

<br> Book III. esp III.15-.34 (III.17  was Friday and Monday's in class assignment)
 
<br>Reader: pp. 1-15.

<br> Pillars: ch 1-2.
