1.12A Understanding Translations and Reflections

What is a translation in the context of transformations?

• A change in the size of a shape

• A slide of a shape up, down, left, or right

• A rotation of a shape around a point

• A reflection of a shape over a line

What type of transformation is described as an "additive transformation"?

• Rotation

• Reflection

• Translation

• Dilation

• Horizontal translation

• Vertical translation

• Reflection

• Rotation

In a translation, what remains unchanged about the shape?

• Size and orientation

• Size and position

• Orientation and position

• Size and color

What does it mean for a transformation to be "rigid"?

• The shape changes size

• The shape changes orientation

• The shape remains congruent

• The shape changes color

Which is an example of a horizontal translation of -3?

Which of the following is an example of a vertical translation?

What is the result of reflecting a point over the x-axis?

• The x-coordinate changes sign

• The y-coordinate changes sign

• Both coordinates change sign

• Neither coordinate changes sign

• Vertical translation

• Horizontal translation

• Reflection

• Dilation

Which of the following transformations does not change the shape's congruency?

• Dilation

• Translation

• Rotation

• Reflection
