Final answer:
A rigid motion in the context of rotational motion is when an object maintains its shape and size after the motion. To determine if a transformation is a rigid motion, we need to examine if there's no change in shape or size. Without specific information, it's difficult to determine if the mentioned transformation is a rigid motion.
Step-by-step explanation:
Rigid motion is a type of motion in which an object maintains its shape and size after the motion. In the context of rotational motion, a rigid body rotates without any deformation. So, to determine if a transformation is a rigid motion, we need to examine if the object retains its shape and size after the transformation. If the transformation does not result in any change in shape or size, then it is a rigid motion.
For example: If you rotate a circle around its center, the shape and size of the circle remain the same after the rotation, so this would be a rigid motion.
Without specific information about the transformation you mentioned, it is difficult to determine if it is a rigid motion. Can you provide more details or context?
