Final answer:
A circular movement at a condyloid joint is indicative of a rotation transformation, mapping pre-image M to M' without altering size or shape.
Step-by-step explanation:
The transformation that maps the pre-image M to its new image M' can be identified through specific changes in the position and orientation of the figure. In this context, the following transformations are considered:
- Rotation involves turning the figure around a fixed point without changing its shape or size.
- Reflection flips the figure over a line, creating a mirror image.
- Translation moves the figure from one place to another without altering its orientation or size.
- Dilation changes the size of the figure, but not its shape.
Since the question mentions a circular movement around a condyloid joint, the most likely type of motion would be rotation.
