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: Understand rigid motion

Rigid motion (translation, rotation, reflection) preserves shape and size.

Step2: Analyze each stone

Stone \(7\) is a rectangle. Other stones (except \(7\)) are irregular polygons (not rectangles). Since rigid - motion preserves shape, and no other stone has the shape of a rectangle.

Answer:

\(7\)
