Notes Day 6

  1. 1. Opener: 1. Find the coordinates of the midpoint of PQ with endpoints P(‐8, 3) and Q(‐2, 7). 2. Find XM. X has coordinates (2, 7), and M has coordinates (6, 1). 1
  2. 2. Extra Distance & Midpoint Practice: 1. If CD = 12 and C(4, ‐7) and D(2, y), what's the value of y? 2. If the midpoint of a segment is (8, ‐2) and one of the endpoints is (12, 6), what is the other endpoint? 2
  3. 3. Homework Add‐On: Choose at least 3 of the problems that you got deductions on from  your quiz. Write a new quiz problem that tests the same skill in a similar way  (using a quadratic for example in #15). Solve each problem, showing your work to demonstrate that you  understand your mistakes. If you do more than 3, you may receive some type of reward for your  efforts...  3
  4. 4. Section 1.7: Transformations in the Coordinate Plane Some vocabulary: 1. Transformation: a change in the position, size or shape of a figure 2. Preimage: the original figure 3. Image: the resulting figure after the transformation 4. Reflection: (flip) a transformation across a line 5. Rotation: (turn) a transformation about a point 6. Translation: (slide) a transformation where all points of a figure move the same distance in the same direction 7. Arrow Notation: a way of describing transformations ABC ‐‐> A'B'C' 8. Rule: descriptors for translations ‐ (x, y) ‐‐> (x + a, y + b) 4
