rigid transformations

What is a rigid transformation? Select ALL that apply.

• Translation

• Reflection

• Rotation

• Dilation

When a figure is translated, what is true? Select all that apply.

• The image has the same coordinates as the preimage.

• All the coordinates from the image have moved in the same direction.

• Corresponding segments are parallel.

• The image and preimage are congruent.

• The image is a different size compared to the preimage.

What properties of the preimage are preserved under a rigid transformation? Select ALL that apply.

• Side lengths and distances

• Angle measures

• Perimeter and area

• Coordinates of vertices
