Question

Describing Types of Dilations

Answer 1

Answer:

An enlargement has a scale factor greater than 1 and the image has a longer distance from the point of dilation than the pre-image. A reduction has a scale factor between 0 and 1, and shrinks on the coordinate plane.

Step-by-step explanation:

This is the sample respond on Edg. I just took the assignment and it was right.

Answer 2

Answer:

The key fact about the enlargement, scale factor > 1

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

Step-by-step explanation:

Let us explain what is the dilation?

• 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
