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
