4.3 Scale Factor Practice

Front

A dilation produces a similar figure.

Back

True

Front

If the scale factor is less than one, the new figure will be

Back

a reduction

Front

If the scale factor is greater than one, the new figure will be: a reduction, an enlargement, a scale, not proportional

Back

an enlargement

Back

(-5,-3)

Front

The point A (8, 12) was dilated to become point A' (2, 3). What was the scale factor?

Back

¼

Front

Coordinates of A(3, 6) after dilation of 2?

Back

(6, 12)

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
