Which statement about rigid transformations is true?. . A rigid transformation preserves only the side lengths of a polygon.. .
A rigid transformation preserves only the angle measures of a polygon.. . A rigid transformation preserves both the side lengths and the angle measures of a polygon.. . A rigid transformation preserves neither the side lengths nor the angle measures of a polygon.
A rigid transformation <span>is a transformation of the plane that preserves length. In a rigid transformation the initial shape and the image shape are congruent. </span> Main properties: <span>1. distance (lengths of segments remain the same) </span><span>2. angle measures (remain the same)</span><span> </span><span>
3. parallelism (parallel lines remain parallel)</span><span> </span><span>
4. collinearity (points remain on the same lines)</span><span> </span><span>
5. orientation (lettering order remains the same) </span><span> </span><span>Taking these properties into account, the correct choice is C.</span>
