Rigid Transformation Vocabularies

How is triangle ABC being translated to triangle A'B'C'?

• left 8, up 3

• left 4, up 9

• right 8, down 3

• right 4, down 9

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)

• (x, y) → (x - 2, y + 3)

• (x, y) → (-x, -y)

• (x, y) → (x + 2, y + 3)

• (x, y) → (x + 3, y -2)

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.

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

• The line of reflection is the perpendicular bisector of corresponding vertices.

• Corresponding vertices are equidistant from the line of reflection.

• The image moves a specified distance to the right, left, up or down.

• The image and preimage are congruent.

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

Determine the translation from triangle ABC to triangle A'B'C'.

Triangle A is rotated 90° clockwise with the origin as the center of rotation to create a new figure. Which triangle shows the new location?

• A

• B
