2. Page 37 Unit 1, Lesson 5: Coordinate Moves
Let’s transform some figures and see what happens to the coordinates of points.

5.1: Translating Coordinates
Select all of the translations that take Triangle T to Triangle U. There may be more than one correct answer.
Write your movements below each question.
 Translate Up 2, Right 4.

3. Page 39 1. Here is a list of points: A = (0.5 , 4) B = (-4 , 5)
C = (7 , -2)
D = (6 , 0)
E = (0 , -3)
On the coordinate plane:
a. Plot each of the five points and label each with its coordinates. b. Using the x-axis as the line of reflection, plot the image of each point. *See red dashed line*
c. Label the image of each point (A’, B’, C’, D’, E’. Include the coordinate for each new point). d. Include a label using a letter. For example, the image of point A should be labeled A’ .
A (0.5, 4)

4. A translation ? A rotation ? A reflection ?
In just a moment, you will be working on two Problem Cards.
Without knowing where your transformation will end up, what would need to know if performing the following movements?
TRANSFORMATION:
A translation ?
A rotation ?
A reflection ?

5. Step 1: Translation
Two steps are required for Problem Card Two steps are required for Problem Card 2.

7. Talk with your partner.
Discuss each of the five sequences shown. Determine which sequences could map Figure P to Figure Q.

8. Rotation Translation Reflection Reflection
If the move is not a rotation, describe the type of transformation you think works:
Rotation
Translation
Reflection
Reflection

9. Rotation (180 degrees)
Reflection (Vertical)
Translation (Down 3, Right 3)
