Question

Ms. Hussain told her class that some dilations make figures bigger, some make figures smaller, and some make figures stay the same size.

Select two of the scale factors that support Ms. Hussain's claim that some dilations make figures smaller.

Answer 1

To make the figures smaller, scale factor must be divided.

Explanation:

1) Firstly, consider a pentagon ABCDE, if we take the scale factor 1\3, the dilations will be smaller.

As distance between A and B = 6

after dilation, distance between A' and B' = 2

Similarly continuing for each side, we get the figure smaller A'B'C'D'E' which is smaller than the original figure.

2) Secondly, consider a hexagon ABCDEF, if we take scale factor 1\2, the dilated figure will be smaller.

A s distance between A and B = 4

After dilations, distance between A' and B' = 2

Similarly continuing for each side, we get the figure A'B'C'D'E'F' which is smaller than the original figure.
