Describing Types of Dilations
Sergio039 [100]

Answer:

The key fact about the enlargement, scale factor > 1

The key fact about the reduction, 0 < scale factor < 1

Step-by-step explanation:

<em>Let us explain what is the dilation?</em>

  • A dilation is a transformation that changes the size of a figure.
  • It can become larger or smaller, but the shape of the  figure does not change.
  • The scale factor measures how much larger or smaller  the image will be
  • If the scale factor greater than 1, then the image will be larger
  • If the scale factor between 0 and 1, then the image will be smaller

Enlargement means the image of a figure after dilation is larger than the original figure

Reduction means the image of a figure after dilation is smaller than the original figure

The key fact about the enlargement is that the scale factor of dilation must be greater than 1 ⇒ scale factor > 1

The key fact about the reduction is that the scale factor of dilation must be between 0 and 1 ⇒ 0 < scale factor < 1
