Today we reviewed for the test (on chapter 3) tomorrow!
STUDY:
1) All the postulates and theorems in chapter 3. Go over the proofs of the theorems. See page 807 for a consecutive list.
2) Do the 15 multiple-choice problems on the Handout from Friday. I will choose some to put on the test. I do not promise it will still be in multiple choice form.
3) Do HW Pg 171 #1-11
4) Do Pg795 #1-19. (Problems 1-10 were done today as a pop quiz!)
KEY to P795 #1-19 (IGNORE THE FACT EVERYTHING IS CROSSED OUT...SILLY BLOG!)
1) True; def. alt-ext angles.
2) False (I leave the rest of the reasons for you to figure out!)
3) False
4) True
5) True
6) False
7) True
8) a || b
9) m || n
10) a || b
11) 1/2
12) -8/3
13) -4/7
14) -2
15) Segment FD
16) Segment AC
17) Segment DC
18) 3 steps! A) ...given B) Angle 1 is congruent to angle P; angle 2 is congruent to angle R because of the Corr. Angles Postulate C) Angle P is congr. to angle R because congruence of angles is transitive.
19) 2 perp. lines for 8 right angles (on a spherical surface).
