Geometry - 2nd & 4th blocks

1/21/2018

On Tuesday, 1/16, you were given the Unit 1 Test review packet.  Since we didn't have school the rest of the week, your homework was to complete the entire packet (the only one we haven't covered yet is #16).  Problems #6, 10, 11 & 12 did not have the correct answer listed, so I asked you to provide the correct answer.  We will review on Monday and test on Tuesday.

Schedule for the beginning of this week:
Monday, 1/22 - Review for Unit 1 Test
Tuesday, 1/23 - Unit 1 Test
Wednesday, 1/24 - Start Unit 2

Below are the answers to the Unit 1 test review.
1.  b                   2.  a                3.  c                 4.  d                    5.   c            6. (x+10, y-17)
7.  a                  8.   a                9.   c.              10.  M'(-1,3), R'(-3,6), S'(-8,-4)
11.  (4, -1)         12.  (3, 4)         13.   2               14.  D                15.  A'(9, 4)  B'(-2, 8)
16.  skip for now (we will cover in class on Monday)
17.  either rotation of 180 degrees or reflect over y = x
18.  Rotation 180 degrees           19.  X'(1, 4), Y'(2, 0), Z'(0,0)  X''(1,1), Y''(2, -3), Z''(0, -3)
20.  Translations, rotations and reflections are isometries because the pre-image is congruent to the image.  All corresponding angles AND all corresponding sides from the pre-image and image are the SAME measure.  Dilations are not isometries because although all corresponding angles are the SAME measure, the corresponding sides are NOT the same measure.
21.  Similarity means same shape, but different size (size increases or decreases proportionally).
       Congruent means same shape AND same size.
22.  Always             23.  Sometimes       24.  Right 3 and down 2    25.  (x-3, y-6)
26. a.  dilation  b.  translation  c.  rotation  d. reflection  e.  dilation  f.  translation
     g.  rotation  h.  reflection
27.  G(-4,5), E(-4,1), O(2,1)    G'(5,4), E'(1,4), O'(1,-2),  G''(-4,-5), E''(-4,-1), O''(2,-1)
28.  J'(5,1), K'(2,5), L'(3,2)      29. i.  KD    ii.  IMON
30.  Rotation 90 degrees counter clockwise or rotation 270 degrees clockwise.
