Question

1. describe a sequence of transformations to move the pre - image (shaded) onto the corresponding image (unshaded). pair a: pair b: pair c: pair d:

Explanation:

Pair A:

Step1: Identify horizontal shift

Count the number of units moved horizontally. The pre - image moves 6 units to the right.

Step2: Identify vertical shift

Count the number of units moved vertically. There is no vertical shift.

Pair B:

Step1: Rotation

The pre - image is rotated 90 degrees clockwise about a point.

Step2: Translation

After rotation, it is translated to the right and down to match the image position.

Pair C:

Step1: Reflection

The pre - image is reflected over a vertical line.

Step2: Translation

After reflection, it is translated down to match the image.

Pair D:

Step1: Dilation

The pre - image is dilated by a scale factor to reduce its size.

Step2: Translation

After dilation, it is translated to the right to match the image.

Answer:

Pair A: Translate 6 units to the right.
Pair B: Rotate 90 degrees clockwise and then translate.
Pair C: Reflect over a vertical line and then translate down.
Pair D: Dilate and then translate to the right.
