Dilations Practice

Front

What do we call a figure BEFORE a transformation is performed?

Back

Pre-Image

Front

This tells us how much farther away from, or closer to the center of dilation points will move:

Back

Scale Factor

Front

This is a fixed point that is the starting point for all dilations:

Back

Center of Dilation

Front

A non-rigid transformation that moves a point along a line by changing the distance from a fixed point is called a:

Back

Dilation

Front

Dilations preserve side length and angle measure. True or False?

Back

False

Front

What is the effect of a scale factor greater than 1 in a dilation?

Back

The figure enlarges.

Front

What is the effect of a scale factor between 0 and 1 in a dilation?

Back

The figure shrinks.

Front

If the center of dilation is at the origin (0,0), how do you find the coordinates of the dilated point?

Back

Multiply the original coordinates by the scale factor.

Front

What is the relationship between the pre-image and the image in a dilation?

Back

The image is a scaled version of the pre-image.

Front

In a dilation, if the scale factor is negative, what happens to the figure?

Back

The figure is reflected and scaled.
