Question

The blue rectangle undergoes a dilation that centers at (0, 0). What is the scale factor used in the transformation? Describe the effect of the scale factor on the blue rectangle's transformation.

A) The scale factor is 2. The blue rectangle enlarges by a factor of +2 and rotates 180°.
B) The scale factor is −2. The blue rectangle enlarges by a factor of +2 and rotates 90°.
C) The scale factor is −2. The blue rectangle enlarges by a factor of +2 and rotates 180°.
D) The scale factor is −2. The blue rectangle shrinks by a factor of
1
2
and rotates 180°.

Answer 1

The correct solution should be:

A) The scale factor is 2. The blue rectangle enlarges by a factor of +2 and rotates 180°.
