Question

which of the numbered stones shown cannot be mapped to another with a rigid motion? stones cannot be mapped to another stone with a rigid motion. (type whole numbers. use a comma to separate answers as needed.)

Explanation:

Step1: Recall rigid - motion concept

Rigid motions (translations, rotations, reflections) preserve shape and size. We need to visually inspect each stone's shape.

Step2: Compare stone shapes

By observing the picture, we look for stones that have a unique shape compared to others. Stone 4 has a distinct shape that cannot be made to match any other stone's shape through a rigid - motion.

Answer:

4
