Example Question #41 :Congruence

Given a circle that is divided intoequal pieces, what is the number of rotations that can occur to keep symmetry?

Possible Answers:

Correct answer:

Explanation:

To calculate the number of symmetrical rotations, take one piece and rotate it clockwise until, it results in the exact image as originally started with. Since the circle is divided intoequal pieces that means that rotating one of the pieces can be donedifferent times and still keep rotational symmetry, which also means keeping the angles of each piece the same and returning to the original image.
