Dilation Techniques on the Coordinate Plane

What is the first step in dilating an object on the coordinate plane?

• Locate the center of dilation

• Draw the new object

• Measure the distance between points

• Determine the scale factor

If the center of dilation is at (-12, -10) and the scale factor is 4, how many times do you repeat the process of moving over 2 and up 2 to find the new location of point A?

• 5 times

• 2 times

• 4 times

• 3 times

To find the new location of point B, how many times do you repeat the process of moving over 2 and up 5?

• 5 times

• 2 times

• 3 times

• 4 times

What is the new location of point C after dilation if you move over 5 and up 2 four times?

• (-1, 6)

• (-2, 4)

• (-5, 1)

• (-7, -2)

What is the distance of line segment AC in the dilated triangle if the original distance is 3 and the scale factor is 4?

• 6

• 9

• 12

• 15

What is the new distance from the center of dilation to point D if the original distance is 6 and the scale factor is 3?

• 15

• 18

• 21

• 12

How many units above the new location of point A is the new location of point B if the original distance is 3 and the scale factor is 3?

• 12 units

• 6 units

• 9 units

• 15 units

What is the new location of point C if it is originally 4 units to the right of point B and the scale factor is 3?

• 8 units to the right

• 10 units to the right

• 12 units to the right

• 14 units to the right

If the center of dilation is at (13, 13) and the scale factor is 2, what is the new distance from the center to point Y if the original distance is 4?

• 10

• 6

• 8

• 12

What is the new location of point Z if you move over 1 and down 4 twice?

• (12, 9)

• (14, 5)

• (15, 3)

• (16, 1)
