Problem 149 of 7
Find a rigid-motion sequence mapping preimage vertices 1, 1; 3, 1; 1, 2 to image vertices 1, -1; 3, -1; 1, -2.
Using a hint is okay. It just tells the trainer to give you a little more review.

find sequence preserving size and shape.
Hidden until you reveal it.
Preimage and image figures must be congruent and related by rigid motions only.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Compare side lengths and orientation to confirm rigid motion is possible.
2. Test translations, reflections, and rotations against corresponding vertices.
3. State a sequence that maps every preimage vertex to its image.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Sequences using dilation when figures are congruent and same size.
