ANSWER:
A: The radii of circle A and circle A' have the same lengths
B: Circle A and circle A' have the same circumference.
C: Circle A and circle A' have the same area.
Explanation:
A figure, when reflected, does not lose any of its arithmetic characteristics, since it does not have any type of dilation or change in its figure.
This means that it conserves its radius, and by conserving its radius it conserves the circumference and the area.
Therefore, the correct answers are:
A: The radii of circle A and circle A' have the same lengths
B: Circle A and circle A' have the same circumference.
C: Circle A and circle A' have the same area.
