Exploring Dilations on the Coordinate Plane

If a point W has coordinates (1,1) and is dilated by a factor of 2, what are the new coordinates?

• (2, 1)

• (0, 0)

• (1, 1)

• (2, 2)

What happens to a figure when it is dilated with a scale factor greater than 1?

• It remains unchanged

• It becomes smaller

• It rotates

• It becomes larger

What is the result of a dilation with a scale factor between 0 and 1?

• Rotation

• Enlargement

• Reduction

• Translation

How does a scale factor of 2/5 affect the size of a figure?

• It reduces the size to less than half

• It doubles the size

• It makes no change

• It increases the size by 2/5

For a dilation with a scale factor less than 1, which of the following is true?

• The figure enlarges

• The figure rotates

• The figure reduces in size

• The figure translates

When dilating a figure, if the scale factor is a fraction less than 1, what type of dilation occurs?

• Reduction

• Translation

• Rotation

• Enlargement

What is the scale factor if the preimage coordinates (1,2) become (3,6) in the image?

• 2

• 1/3

• 1/2

• 3

In a dilation about the origin, what relationship do the pre-image, image, and origin have?

• They are concentric circles

• They form a right angle

• They are collinear

• They form an equilateral triangle

What does a scale factor of 3/4 indicate about the dilation?

• It is an enlargement

• It is a reduction

• It is a rotation

• It is a reflection

If a rectangle is dilated with a scale factor of 3/4, what happens to its area?

• It remains the same

• It increases by 1/4

• It triples

• It decreases
