What rule maps Rectangle RUST onto Rectangle R’U’S’T’ ?

• f (x,y) → (x - 3, y + 5)

• f (x,y) → (x - 5, y + 3)

• f (x,y) → (x + 5, y - 3)

• f (x,y) → (x + 3, y - 5)

The triangle 1 is transformed as shown in the diagram, resulting in triangle 3.

What are the transformations?

• Reflection, then translation

• Translation, then reflection

• Dilation, then reflection

• Rotation, then translation

A parallelogram has vertices at (0, 0), (0, 6), (4, 4), and (4, -2).

Which transformation maps the parallelogram to itself?

• A reflection across the line x = 2

• A rotation of 180° about the point (0, 0)

• A rotation of 180° about the point (2,2)

• A reflection across the line y = 2

Which of the following best describes a geometric rotation?

• A transformation that enlarges or reduces the size of a figure by a certain scale factor.

• A transformations that slides a figure to a new location.

• A transformation that flips a figure across a line.

• A transformation that turns a figure around a point.

Which of the following statements is the definition of parallel lines?

• Two distinct coplanar lines that do not intersect.

• Two distinct coplanar lines that intersect at a 90°angle.

• Two rays with a common endpoint that point in opposite directions.

• Two rays sharing a common endpoint.
