Question

Determine the direction and degree of rotation used to create the image.

90° counterclockwise rotation
270° clockwise rotation
90° clockwise rotation
180° counterclockwise rotation

Answer 1

Answer: 90° clockwise rotation

Explanation:

The rules for rotation are below:

90° clockwise rotation = (x, y)→(y, -x)

270° clockwise rotation = (x, y)→(-y, x)

180° counterclockwise rotation = (x, y)→(-x, -y)

90° counterclockwise rotation = (x, y)→(-y, x)

Let's take point B. Point B's coordinates are (3, -2). Point B' is (-2,-3). -x would be -3, and y stays the same.

Therefore, the answer is 90° clockwise rotation.
