Question

Which of these properties of a rigid transformation is exclusive to translations? A. The measures of the angles and sides in the preimage are preserved. B. The points in the preimage lie in the same plane as the points in the image. C. All the points in the preimage are shifted the same distance. D. The orientation of sequences of points in the preimage are always preserved.

Answer 1

A rigid transformation is a type of transformation of the plane that preserves the size and shape of the image. When reflections, translations, rotations are combined, this results to rigid transformations. The pre-image and the post-image are congruent except in the orientation. Answer thus is A.
