SUNY at Stony Brook MAT 515:
Fall 2013
Schedule MAT 51510
Week Sections of the book to read in advance
HW # Homework (Problem in bold must be  submitted on Wednesdays for grading)
Remarks
8/26 Introduction
1. Angles
2. Perpendicular lines
3. Propositions
1
31, 34, 38, 40,45, 47,51, 54, 57, 58 (note: in 58 an intersection point should be an intersection of at least two lines)
Here is a short and nice account of the subject.
Here are the slides. Here is homework 0.
9/2 4. Polygons and triangles


2 52, 53, 56,59,60, 61.
9/2 Labor day - no class
Homework 0 and 1 are due 9/4.
9/9 5. Isosceles triangles and symmetry.
6. Congruence tests for triangles.
3
62, 63, 64, 65, 67, 70,71, 72, 74, 77, 79, 80, 84, 85.
In problem 62 to 74 you cannot use congruence of triangles (SAS, ASA etc)
Homework 2 is due 9/11.
9/16 7. Inequalities in triangles
4
86, 87, 89, 90, 92, 94
NOTE:
In problem 89 where it says "greater" it should say "smaller"
.
In problem 94 where it says "smaller" it should say "greater".
Can you proof that  89 and 94, as stated in the book, are false?



In a separate page, write in your own words (English words, no symbols) a summary of the postulates and theorems in Sections 1 to 7 (including 7).
For each theorem write a SHORT (about one - two - three sentences) idea of the proof (e.g,it uses symmetry, and/or the postulate "there is a unique line passing through  any two distinct  points ").
Number the theorems so you refer to these numbers when a statment is used in the proof of another theorem.
(This summary is part of  homework 4)

Homework 3 is due 9/18.
On Wed 9/18 the class will take place at the SCGP. (see here) Homework 3 will be collected there.
9/23 8. Right triangles.

Review.
5
96, 97, 98, 101
Read Section 8 (Rigth triangles) before doing the homework.
Homework 4 is due 9/25.
9/30 9. Segment and angles bisectors.

6
106, 109, 110, 111, 112.
Write down the proofs of these statements with appropriate justification (appropriate means providing only the relevant and necessary steps to obtain the proof).
DO NOT use symbols or abreviations, with the exception of <, >, +, =, symbol for angle, symbol for congruence and other symbols that for parts of formulae.
Use complete English sentences.
Here are good guidelines for proof writing.
After your finish writing your problems, read them out loud, to be sure that the English is correct, and that what your wrote is mathematically correct.
Correct writing (in the sense just explained) will be part of the grade from now on.


Homework 5 is due 10/2.
