### Midterm Review: Day 3 - White Board GP - Rotations & Dilations

1. 1. + White Board Midterm Review #2! Play by the rules and follow the directions!
2. 2. + What are the new coordinates if (4, 3) is translated 8 units left and 4 units up?
3. 3. + What type of transformation turns a preimage onto an image?
4. 4. + If a point starts in Quadrant I and is rotated 270° clockwise, in what quadrant would you be?
5. 5. + If a point starts in Quadrant III and is rotated 90° counter-clockwise, in what quadrant would you be?
6. 6. + What type of transformation enlarges or reduces a preimage to an image?
7. 7. + What makes a dilation be a reduction?
8. 8. + What makes a dilation be an enlargement?
9. 9. + In triangle XYZ, point Z has coordinates of (24, -7). If the triangle undergoes a dilation with a scale factor of ½, what are the coordinates of Z’?
10. 10. + If the formula to determine the coordinates of an image after a dilation is: Preimage x Scale Factor = Image What is the formula to solve for the scale factor in a dilation?
11. 11. + Preimage coordinates: A(4, 6) B(-2, 5) C(0, -3) Image coordinates: A’(16, 24) B’(-8, 20) C’(0, -12) Calculate the scale factor of the dilation!
