Enlargement | arrow_right_alt | A fixed point from which a dilation is generated |
Reduction | arrow_right_alt | When the scale factor is greater than 1, the image created is larger than the pre-image |
Center of Dilation | arrow_right_alt | When the scale factor is less than 1, the image created is smaller than the pre-image |

Scale Factor | arrow_right_alt | Transformations that produce figures that are the same shape as the original figure, but not the necessarily the same size |
Similar | arrow_right_alt | The ratio of the distance of the new figure from the center of dilation to the distance of the original figure from the center of dilation. Written as a fraction of the new figure compared to the original figure. |
Dilation | arrow_right_alt | When two figures ratios of corresponding side lengths are equal |

Which statement is true?
A polygon is graphed on a coordinate plane with (x, y) representing the location of a certain point on the polygon. The polygon is transformed using the rule (x, y) → (ax, ay).
Which statement must NOT be true?
