Rotation and Dilation Review

What is the angle of rotation if a figure is rotated 90 degrees clockwise?

• 45 degrees

• 270 degrees

• 180 degrees

• -90 degrees

Define the center of dilation in a dilation transformation.

• The fixed point about which all other points are dilated or scaled.

• The line that all points are reflected over

• The point that moves randomly during the transformation

• The point that remains fixed during the transformation

If the scale factor of a dilation is 2, what can you say about the enlargement of the figure?

• The figure is enlarged by a factor of 3.

• The figure is enlarged by a factor of 2.

• The figure is reduced by a factor of 2.

• The figure remains the same size.

Explain the concept of enlargement in a dilation transformation.

• Enlargement involves dividing the coordinates by a scale factor greater than 1.

• Enlargement is achieved by multiplying the coordinates by a scale factor less than 1.

• Enlargement in dilation results in shrinking the object.

• Enlargement in dilation involves multiplying the coordinates of the original object by a scale factor greater than 1.

Calculate the angle of rotation if a figure is rotated 180 degrees counterclockwise.

• 90 degrees

• 360 degrees

• 180 degrees

• 270 degrees

How does the center of dilation affect the size of the dilated figure?

• The center of dilation has no impact on the size of the dilated figure.

• The center of dilation determines the color of the dilated figure.

• The center of dilation determines the scale factor for enlargement or reduction.

• The center of dilation affects the rotation of the dilated figure.

If the scale factor of a dilation is 0.5, how does it impact the size of the figure?

• The figure is reduced to half of its original size.

• The figure is enlarged to double its original size.

• The figure is reduced to one-fourth of its original size.

• The figure remains the same size.

Describe the relationship between the scale factor and the enlargement in a dilation transformation.

• The enlargement is determined by the rotation angle, not the scale factor.

• The scale factor has no impact on the enlargement in a dilation transformation.

• The scale factor determines how much larger or smaller the image will be after the dilation.

• The scale factor directly affects the translation, not the enlargement.

Determine the center of dilation if a figure is dilated by a scale factor of 3.

• (1,1)

• (3,3)

• (2,2)

• (0,0)

In a dilation transformation, how does the angle of rotation affect the final orientation of the figure?

• The figure will be translated horizontally.

• The figure will be rotated 180 degrees.

• The angle of rotation does not affect the final orientation of the figure.

• The figure will be reflected over the x-axis.
