Dilation Transformations

When you dilate the figure by a scale factor of 3, what is the location of B'?

• (12,0)

• (12,12)

• (4,3)

• (0,12)

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 original photo has side lengths of 5 inches and 6 inches. He is wanting to dilate the picture by a scale factor of 2. How many total inches of wood will he need to create a frame for the new enlarged photo?

• 22

• 44

• 88

• 121

Which transformation is NOT an isometry?

• translation

• reflection

• rotation

• dilation

What is the scale factor if Point P is at (-2, 3) and P’ is at (-8, 12)?

• 6

• 9

• 8

• 4

Identify the transformation

• Dilation

• Translation

• Reflection

Which rule would dilate shows a scale factor of 4

• (x, y) → (y, x)

• (x, y) → (x + 4, y + 4)

• (x, y) → (x, -y)

• (x, y) → (4x, 4y)

Does the image show a Dilation? If yes, did the image enlarge, reduce or none of the above?

• Yes, enlarge

• Yes, reduce

• No

For the figure shown, which point would be closest to center of dilation?

• (5, 7)

• (-8 1)

• (-1, 4)

• (0, 5)

Dilate Point B by a scale factor of 3:

• (12,0)

• (12,12)

• (4,3)

• (0,12)
