Rotation Dilation Review

If you were to rotate ABCD 180° about the origin, what would the coordinate of A' be?

• (3, 5)

• (-3, -5)

• (-5, 3)

• (5, 3)

What is the image of J (8, -6) after a rotation of 180° counterclockwise?

• J' (8, 6)

• J' (-6, 8)

• J' (-8, 6)

• J ' (-8, -6)

Rotate K (7, 8) around the origin 90° counterclockwise. State the image of K'.

• K' (-7, -8)

• K' (8, -7)

• K' (-8, 7)

• K' (8, 7)

What is the image of S (2, -5) after a rotation of 90° clockwise about the origin?

• S' (-5, -2)

• S' (5, -2)

• S' (-2, 5)

• S' (5, 2)

What is the image of M (4, -8) after a rotation 270° clockwise?

• M' (-8, 4)

• M' (8, 4)

• M' (-4, -8)

• M' (-8, -4)

Dilate Point B by a scale factor of 3:

• (12,0)

• (12,12)

• (4,3)

• (0,12)

Choose the correct scale factor:

• 2

• 3

• 1/3

• 1/2

If the scale factor is greater than one, the new figure will be

• a reduction

• an enlargement

• a scale

• not proportional

Dilate Point B by a scale factor of 1/2

• (1.5,-4)

• (-1.5,1)

• (-1,-1.5)

• (-2,-2)

The point (8, 12) was dilated to become point (2, 3). What was the scale factor?

• ½

• ¼

• 4

• 2
