Exploring Dilations and Similar Figures in Geometry

What is the last type of transformation discussed in the video?

• Translation

• Dilation

• Rotation

• Reflection

Which type of motion is a dilation considered to be?

• Non-rigid motion

• Rigid motion

• Isometry

• Congruent motion

What does a similarity transformation involve?

• Only translations

• A combination of rigid motions and dilations

• Only rotations

• Only reflections

What is preserved in a dilation?

• Size

• Shape

• Neither size nor shape

• Both size and shape

How is the scale factor represented in calculations?

• As a difference

• As a sum

• As a product

• As a fraction

If the scale factor (k) is greater than 1, what type of dilation is it?

• Translation

• Isometry

• Enlargement

• Reduction

In a dilation, if the image is smaller than the pre-image, what is the range of the scale factor (k)?

• k = 1

• k < 0

• k > 1

• 0 < k < 1

What is the scale factor if the distance from the fixed point to the image is 4 and to the pre-image is 12?

• 1/4

• 1/3

• 3

• 4

When graphing a dilation with a scale factor of 3, what happens to the size of the figure?

• It flips upside down

• It enlarges to three times

• It remains the same

• It reduces to one-third

What is the first step in graphing a dilation if no fixed point is mentioned?

• Ignore the fixed point

• Use the midpoint of the figure

• Choose any random point

• Assume the fixed point is the origin
