Exploring Dilations and Coordinate Notation

What is true about the pre-image and image in a dilation?

• They are congruent.

• They are similar.

• They are identical.

• They are complementary.

What happens to a figure when the scale factor is between 0 and 1?

• It is reduced.

• It remains the same.

• It is enlarged.

• It is rotated.

What happens to a figure when the scale factor is greater than 1?

• The figure remains unchanged.

• The figure is reduced.

• The figure is enlarged.

• The figure is rotated.

What is the scale factor if the image and pre-image are the same size?

• 1

• 0

• Between 0 and 1

• Greater than 1

What does a negative scale factor indicate in dilations?

• Negative scale factors are not possible.

• The figure is reflected.

• The figure is rotated.

• The figure is translated.

What is the role of the center of dilation in a dilation on a coordinate plane?

• It determines the shape of the image.

• It has no role in dilations.

• It is the fixed point from which the dilation is measured.

• It changes the color of the image.

How does the distance from the center of dilation change with a scale factor of 2?

• It becomes zero.

• It is doubled.

• It is halved.

• It remains the same.

What is the result of a dilation with a scale factor of 1/2?

• Rotation

• Reduction

• Enlargement

• Translation

How do you describe a dilation using coordinate notation?

• By multiplying each coordinate by the scale factor.

• By subtracting the scale factor from each coordinate.

• By adding the scale factor to each coordinate.

• By dividing each coordinate by the scale factor.

If a triangle's coordinates are multiplied by 3, what is the scale factor?

• 1/3

• 3

• 0

• 1
