A _________________ is a transformation that turns a figure clockwise or counterclockwise about a

fixed point for a given angle and a given direction.

• formation

• radius

• rotation

• reflection

Which statement is true?

• After a 180° rotation, parallelogram R’S’O’T’ will be congruent, the orientation of coordinates will

  be preserved, and will land in Quadrant III.

• After a 180° rotation, parallelogram R’S’O’T’ will not be congruent, the orientation of coordinates

  will be preserved, and will land in Quadrant II.

• After a 180° rotation, parallelogram R’S’O’T’ will be congruent, the orientation of coordinates will

  be preserved, and will land in Quadrant IV.

• After a 180° rotation, parallelogram R’S’O’T’ will be congruent, the orientation of coordinates will

  not be preserved, and will land in Quadrant III.

A figure was transformed on a coordinate grid. The coordinate for the vertex of the preimage was (–5, 3)

and the image coordinate was recorded at (5, –3). Which of the following describes the transformation?

• a reflection across the y-axis

• a rotation of 270° clockwise about the origin

• a translation 6 units to the left

• a 180° rotation about the origin

If you were to rotate ABCD 180°  about the origin, what would the coordinate of A' be?

(a)  

• (-5, 5)
• (-3, -5)
• (-5, 3)
• (-3, 3)
