Transformations Rotation Translation and Dilation

A type of transformation where a geometric figure slides horizontally, vertically, or both.

• dilation

• translation

• rotation

• reflection

The following is a ...

• Translation

• Reflection

• Rotation

• Dilation

Determine how to translate triangle A'B'C' to triangle ABC.

• (x+2, y-5)

• (x+2, y-9)

• (x-2, y-9)

A dilation is which of the following: 

• only an enlargement

• only a reduction

• Either an enlargement or a reduction

• Neither an enlargement or a reduction

In a dilation what mathematical operation is used with the scale factor?

• addition 

• subtraction 

• multiplication 

• division 

Select all transformations that result in a CONGRUENT image.

• translation, then dilation of 2

• translations up 2, then translation right 4

• vertical translation, then reflection over the x-axis

• reflection over the x-axis, then dilation of 1/2

• dilation of 3, then rotation 90 degrees counter-clockwise

This type of transformation changes the size:

• rotation

• translation

• reflection

• dilation

Rotations, Reflections and Translations are known as _________. These transformations create CONGRUENT images that are the same size and shape.

• Similarity Transformations

• Rigid Transformations

• Resizing Transformations

Translated figures are always __________________.

• Congruent

• Bigger

• Smaller

• Rotated

A transformation that “turns” a figure about a fixed point is a _____________________.

• rotation

• translation

• reflection

• dilation
