Question

Square ABCD was dilated to form square A’B’C’D’. Is this a reduction or an enlargement? What scale factor was used? (3 points)

Answer 1

As you can see ABCD is larger than A'B'C'D'.

25%

Answer 2

The scale factor is the ratio of the lengths, not the area, so in this case the scale factor is 1/2.
