Transformations and Rotations

What is the definition of rotation?

• To move up, down, left, or right.

• To flip.

• To make a circular movement around a point.

• To mirror.

Which is the algebraic representation for a rotation 180 degrees clockwise?

• (y, x)

• (-y, x)

• (y, -x)

• (-x, -y)

Which transformation will always produce the same image as a rotation 90 degrees counterclockwise?

• A reflection over the y-axis

• A rotation 270 degrees clockwise

• A rotation 90 degrees clockwise

• A reflection over the x-axis
