Question

Which of the following does not describe a rigid motion transformation? A. translating a figure 2 units left. B. rotating a figure 90 degrees. C. reflecting a figure across the x-axis. D. dilating a figure by a scale factor of one half

Answer 1

Answer: D, dilating a figure by a scale factor of one half

Answer 2

Rigid motion is the way of moving an object such that after the motion the relative distance between the points stay the same in the same way that the relative position is the same. The answer to this question is dilating the figure by a scale factor of one half.
