Transformations Math

Identify a rule to describe the transformation.

• translate right 1, up 3

• translate left 1, down 3

• reflected in x-axis

• reflected in y-axis

Quadrilateral A’B’C’D’ is the image of quadrilateral ABCD under a rotation about point Q. Determine the angle(s) of rotation. Select all that apply.

• 90° Clockwise

• 90° Counterclockwise

• 180° Clockwise

• 270° Clockwise

• 270° Counterclockwise

Scooby-Doo’s friends are at the four corners of a quadrilateral with points and images as follows for a rotation of 180° about the origin. Scooby-Doo says

this is the correct coordinates. Is he correct?

• No, he did a 90° clockwise rotation.

• Yes, he did the correct steps for 180° rotation.

• No, he did a 270° clockwise rotation.

A (translation / reflection) is a transformation that moves every point of a figure the same distance and in the same direction.

• Translation

• Reflection

The (point / image) is the figure you get after a transformation.

• point

• image

A (line of symmetry / angle of rotation) is the number of degrees a figure is rotated.

• line of symmetry

• angle of rotation

When reflecting across the y-axis, the (x-coordinate / y-coordinate) stays the same.

• x-coordinate

• y-coordinate

Reflect ΔABC over the y-axis. Using prime notation to label the image list the coordinates of C’.

• C' (-3, 1)

• C' (-3, -1)

• C' (3, 1)

• C' (3, -1)

• x-axis

• y-axis

• neither

Translate F(4,-5) left 2 and up 3.

State the coordinates of F’.

• F' (2, -2)

• F' (2, 2)

• F' (-2, -2)

• F' (-2, 2)
