True or False: A dilation produces a similar figure.

Back

True

Front

What is the definition of the figure before a transformation occurs? (Options: Pre-image, Image, Translation, Reflection)

Back

Pre-image

Front

Dilate the figure by a scale factor of 3 with the origin as the center of dilation. What are the coordinates of the image for A(3,3), B(6,6), C(9,3)?

Back

A'(9,9) B'(18,18) C'(27,9)

Front

What is a scale factor in dilation?

Back

A scale factor is a number that scales, or multiplies, the dimensions of a figure.

Front

Back

Reduction

Front

If the scale factor is greater than 1, what type of transformation occurs?

Back

Enlargement

Front

What is the center of dilation?

Back

The point about which a figure is enlarged or reduced.

Front

What happens to the angles of a figure during dilation?

Back

The angles remain the same.
