Answer:
The transformation is rigid because the corresponding side lengths and angles are congruent.
Step-by-step explanation:
Since we have congruent triangles (not similar triangles), they will have to have the same length and angles throughout your transformation. Therefore, our answer is the 1st Option.
C. (-1, -2) would be your answer
That transformation is just a translation (x-2, y-4) from point (1,2)
