Example Question #11 : Rotation, Reflection, And Transformation Definitions: Ccss.Math.Content.Hsg Co.A.4
Given a circle that is divided into equal pieces, what is the number of rotations that can occur to keep symmetry?
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 into equal pieces that means that rotating one of the pieces can be done different times and still keep rotational symmetry, which also means keeping the angles of each piece the same and returning to the original image.
Therefore the correct answer is .
