Ch.9 Review

The original figure in a transformation is called the

• translation

• preimage

• image

• transformation

• rigid motion

Mapping that results in a change in the position, shape, or size of the figure is called a

• translation

• preimage

• image

• transformation

• rigid motion

The resulting figure in a transformation is called the

• translation

• preimage

• image

• transformation

• rigid motion

A transformation that preserves distance and angle measures is called a

• rigid motion

• preimage

• image

• transformation

A transformation that maps all points of a figure the same distance in the same direction

• translation

• preimage

• image

• transformation

• rigid motion

A combination of 2 or more transformations is called a

• translation

• preimage

• party

• composition of transformations

• rigid motion

For a dilation, if the scale factor n is greater than 1 then the resulting image is a(n)

• reduction

• enlargement

• scale factor

• dilation

For a dilation, if the scale factor n is less than 1 then the resulting image is a(n)

• reduction

• enlargement

• scale factor

• dilation

A dilation image cannot have any points in common with its pre-image

• True

• False

To find the scale factor of a dilation you should

• Use the ratio of corresponding sides with the image as the numerator and the pre-image as the denominator

• Use the ratio of corresponding sides with the pre-image as the numerator and the image as the denominator

• Count the sides of the figure

• Find the Area of the figure
