Answers:
- translation 1 unit left, 1 unit down
- reflection across y-axis
- dilation with the scale factor of 1/2
Step-by-step explanation:
We will mark the transformations that map the blue figure into the green figure.
✗rotation 90 degrees clockwise
➜ No, if you rotate L 90 degrees clockwise it doesn't line up with R.
✗ rotation 180 degrees clockwise
➜ No, if you rotate L 180 degrees clockwise it doesn't line up with R.
✓ translation 1 unit left, 1 unit down
➜ Yes, this figure is moved down.
✗ dilation with a scale factor of 2
➜ This shape is getting smaller, not bigger.
✓ reflection across y-axis
➜ Yes, this is true.
✗ reflection across x-axis
➜ This shape is reflected across the y-axis, not the x-axis.
✗ translation 1 unit right, 1 unit up
➜ No, this figure is not moved up.
✓ dilation with the scale factor of 1/2
➜ Yes, this is true. The bottom length gives 6 * 1/2 = 3.
