Rigid or Nonrigid Transformations

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

Given the original coordinates (-3, 1), (-4, -3), (-1, 1), rotate them 180 degrees about the origin. Then, dilate by a factor of 2 about the origin.

• (6, -2), (8, 6), (2, -2)

• (0, -7), (-6, 8), (3, -6)

• (2, -6), (0, -3), (6, 8)

• (0, -2), (-2, -6), (6, -8)

Answer explanation

Rotate the coordinates 180 degrees: (-3, 1) -> (3, -1), (-4, -3) -> (4, 3), (-1, 1) -> (1, -1). Dilate by a factor of 2: (3, -1) -> (6, -2), (4, 3) -> (8, 6), (1, -1) -> (2, -2). Therefore, the correct answer is (6, -2), (8, 6), (2, -2).

The coordinates of a figure are A(1, 3) B(-3, -1) C(2, -2) is being dilated by a scale factor of 2 with the origin as the center of dilation.

Plot the coordinates of the image?
