Reduction | arrow_right_alt | A fixed point from which a dilation is generated |
Center of Dilation | arrow_right_alt | When the scale factor is greater than 1, the image created is larger than the pre-image |
Enlargement | 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 transformation does NOT preserve congruence?
A polygon is graphed on a coordinate plane with (x, y) representing the location of a point on the polygon. The polygon is transformed using the rule (x, y) → (ax, ay).
Which statement must be true?

Quadrilateral PQRS is dilated with the origin as the center of dilation to create quadrilateral P′Q′R′S′.
What scale factor was used to dilate quadrilateral PQRS?
A trapezoidal door mat is similar in shape to a trapezoidal rug. Each dimension of the door mat is one-third the size of the rug.
By what factor is the area affected?
Quadrilateral KMPT is dilated by a scale factor of 3/4 to create quadrilateral K’M’P’T’. The perimeter of quadrilateral KMPT is 60 units.
What is the perimeter, in units, of quadrilateral K’M’P’T’?
