Transformations Test

Melanie wants to create a pattern using a

transformation that will change the orientation of

a figure but not the orientation of the vertices.

Which transformation should she use?

• Dilation

• Reflection

• Rotation

• Translation

Which algebraic representation shows the

effect that a reflection over the x-axis will have

on the coordinates of a figure?

• (x, -y)

• (-x, y)

• (-x, -y)

• (-y, x)

Record the coordinates of A', B' and C'

The coordinates below represent a triangle

that was dilated.

J(-3, -12) J’(-2, -8)

K(-6, -15) K’(-4, -10)

L(-9, -12) L’(-6, -8)

What was the scale factor that was used in the

dilation?

Which is the correct algebraic representation

of the transformation displayed on the graph?

• (y, -x)

• (-y, x)

• (-x, y)

• (-x, -y)

Which is a not a true statement about the

figures shown below?

• The image is smaller than the pre-image.

• Triangle GHI is similar to Triangle G’H’I’.

• The transformation shown is a dilation.

• Segment GH is congruent to segment G’H’.

Ben is going to rotate a figure in Quadrant IV

90° counterclockwise. In which Quadrant should

the image be?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Luke is going to reflect point R(6, 10) over the

y-axis. What are the coordinates for R’?

The table below shows the coordinates of a

figure that was transformed.

Which is a correct description of the

transformation?

• Rotation 180° clockwise

• Reflection over the x-axis

• Translation 5 units left and 2 units down

• Translation 10 units left and 4 units down

Rotate the figure shown 180° clockwise.

Record the coordinates of the image.
