Question

Parallel lines are preserved in which of the following types of transformations? 1. rotations II. reflections III. translations​

Answer 1

Answer:

All of the above.

Step-by-step explanation:

Translation, reflection, and rotation are isometries, since they preserve length. Therefore translation, reflection and rotation are congruency transformations. Further if we only require that parallel lines be mapped onto parallel lines, we get the shears and stretches.
