Exploring Scale Factors in Dilations

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

• The figure remains unchanged

• The figure is reduced in size

• The figure is rotated

• The figure is enlarged

If a scale factor is 0.5, what happens to the original figure?

• It doubles in size

• It remains the same

• It reduces to half its size

• It becomes zero

If the scale factor is 1/3, what happens to the size of the figure?

• It increases by one-third

• It triples in size

• It remains unchanged

• It reduces to one-third its size

How do you determine the scale factor used in a dilation?

• By adding coordinates

• By dividing coordinates

• By multiplying coordinates

• By subtracting coordinates

What is the scale factor if the original coordinate (2,1) changes to (6,3)?

• 5

• 2

• 3

• 4

If a figure is enlarged, what can be inferred about the scale factor?

• It is negative

• It is less than 1

• It is equal to 1

• It is greater than 1

What indicates a mistake if the original figure enlarges but the calculated scale factor is less than 1?

• The figure should rotate instead

• The original figure should reduce

• The scale factor calculation needs re-evaluation

• The calculation is correct

For a triangle with coordinates (3,2), (7,2), (5,6) dilated by a factor of 4, what are the coordinates of point A'?

• (12, 8)

• (20, 24)

• (14, 8)

• (15, 24)

What operation is performed on the coordinates to achieve dilation?

• Multiplication

• Division

• Subtraction

• Addition

What is the correct set of coordinates for point C' after dilation by a factor of 4?

• (12, 8)

• (28, 8)

• (20, 24)
