Dilations and Scale Factor Practice

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but maintains its shape, defined by a scale factor.

Front

How do you calculate the scale factor of a dilation?

Back

The scale factor is calculated by dividing the coordinates of the image by the coordinates of the preimage.

Front

If the scale factor is less than 1, what type of transformation is it?

Back

It is a reduction.

Front

If the scale factor is greater than 1, what type of transformation is it?

Back

It is an enlargement.

Front

What is the scale factor if point A (8, 12) is dilated to point A' (2, 3)?

Back

Front

What does a scale factor of 2 indicate about a dilation?

Back

It indicates that the image is twice the size of the preimage.

Front

What is the scale factor if a rectangle's length is halved during dilation?

Back

Front

How can you determine if a dilation is an enlargement or a reduction?

Back

If the scale factor is greater than 1, it is an enlargement; if it is less than 1, it is a reduction.

Front

What is the scale factor if a triangle's sides are tripled during dilation?

Back

The scale factor is 3.
