Scale Factor and Dilation Practice

Is this an enlargement or a reduction?

• Enlargement

• Reduction

Scale Factor of 5 is _________________ .

• Reduction

• Enlargement

The point A (8, 12) was dilated to become point A' (2, 3). What was the scale factor?(hint: divide the x-coordinate of the image by the x-coordinate of the preimage).

• ½

• ¼

• 4

• 2

Find the measure of x:

• 6

• 24

• 33

• 36

State the coordinate of the image of the given point B (-10,-6) under a dilation with center at the origin with the given scale factor k = 1/2.

• (5,3)

• (20,12)

• (-20,-12)

• (-5,-3)

The pair of figures is similar. Find the missing side.

• x = 20

• x = 12

• x = 5

• x = 4

Find missing side

• 5

• 7

• 9

• 11

Solve for X.

• 2 ft

• 3 ft

• 4 ft

• 6 ft

If a dilation has a scale factor of 0.5, it can be classified as a(n) ___.
