10/8/15 = GEOMETRY…………………………………………….…………
HW WAS - read the lesson then do P.123 # 1-22 all
Give me your spiral while we listen to our prayer song – then
Let’s grade your HW: GRADE: 22 ANSWERS SO = -4 EACH ANSWER
1.
2. C
4. B
6. ANGLES 4,6 OR 3,5
8. ANGLES 3,6 OR 4,5
10. AI
12. CORR:
1,4 OR 3,7 OR 5,9 OR 4,8 OR 2,6 OR 1,8
14. AE:
1,9 OR 3,10 OR
16. AI
18. CORR
20. SSI
22. SSI
1ST PERIOD IS NOT FOR DOING HW – IT IS TIME TO:
– CHECK EVENS
- ASKING ? AND CLARIFYING AND
- DOING CORRECTIONS
– YOU MUST WORK AS A GROUP AND ASK EACH OTHER QUESTIONS
BEFORE YOU GO TO MR. REICH FOR HELP
– YOU MUST CHECK ODDS AT HOME – WHERE YOU DO YOUR HW.
GEOMETRY CLASS NEEDS TO SIT TOGETHER IN 1ST PERIOD AND DO THIS.
YOU MUST BE ABLE TO SHOW HIM ON PAPER WHERE YOU TRIED IT –
BEFORE YOU CAN ASK FOR HELP – ALL 3 MUST SHOW IT FIRST!!
3.4 PARALLEL LINES AND TRANSVERSALS
TWO LINES AND A TRANSVERSAL
TRANSVERSAL = A LINE THAT CUTS ACROSS 2 OR MORE LINES
P.128
THERE ARE RELATIONSHIPS BETWEEN THESE ANGLES!
CORRESPONDING ANGLES = CORR
=EACH OTHER
ALTERNATE INTERIOR ANGLES = AI
=EACH OTHER
ALTERNATE EXTERIOR ANGLES = AE
=EACH OTHER
SAME SIDE INTERIOR ANGLES = SSI
=180
POSTULATE 8 = CORR ANGLES POSTULATE
THEOREM 3.5 = AI
THEOREM 3.6 = AE
THEOREM 3.7 = SSI
ON THE TEST I WILL GIVE YOU THESE POSTULATE/THEOREMS – ALL OF
THEM FROM THIS CHAPTER 
HOW CAN YOU SOLVE FOR X ?
ANGLES (2X-45) AND (X+30) ARE
CORR!
SO  ARE CONGRUENT  SO I CAN SAY: 2X-45 = X+30
SAW so if there is any work
(MATH) that can be done – I
want to see it – on your
paper!
*HW = TEST TOMORROW ON 3.1-3.4
TONIGHT:
DO P.132 # 1-23 ODDS & CHECK & CORRECT AND
STUDY OVER YOU HW FROM THESE LESSONS 3.1-3.4
*YOU ARE ALWAYS SUPPOSED TO CORRECT ANY HW PROBLEM
THAT YOU GOT WRONG – EVERY DAY/NIGHT
ANSWERS NOT IN THE BACK OF BOOK:
1=corr
2=ai
3=none
4=corr
5=ae
6=corr
7=ssi
13=the measure of all the other angles is 90 degrees – if you have 2
parallel lines cut by a transversal and if one of the angles is 90 then all
of the angles must be 90 due to perpendicular lines and corr angles by
the CORR ANGLES POSTULATE 
