Question

describing rotations each coordinate plane below shows a pre - image and its rotated image. write a sentence to describe each rotation. the first problem has been completed for you. ① triangle abc was rotated 90° counterclockwise around the origin to form triangle abc. ② ③ ④

Explanation:

Step1: Observe the orientation change of the shape in problem 2

By comparing the pre - image and image of the rectangle, we can see the rotation direction and angle.

Step2: Determine the rotation details

The rectangle WXYZ is rotated 180° around the origin to form rectangle W'X'Y'Z'.

Step3: Observe the orientation change of the shape in problem 3

By comparing the pre - image and image of the rectangle JKLM, we can see the rotation direction and angle.

Step4: Determine the rotation details

The rectangle JKLM is rotated 90° clockwise around the origin to form rectangle J'K'L'M'.

Step5: Observe the orientation change of the shape in problem 4

By comparing the pre - image and image of the parallelogram RSTU, we can see the rotation direction and angle.

Step6: Determine the rotation details

The parallelogram RSTU is rotated 180° around the origin to form parallelogram R'S'T'U'.

Answer:

1. Rectangle WXYZ was rotated 180° around the origin to form rectangle W'X'Y'Z'.
2. Rectangle JKLM was rotated 90° clockwise around the origin to form rectangle J'K'L'M'.
3. Parallelogram RSTU was rotated 180° around the origin to form parallelogram R'S'T'U'.
