Answer:
The order of rotational symmetry of the wheel is;
C) 12
Explanation:
The order of rotational symmetry of a shape is given by the sum of the times the shape can by rotated round 360° and still appears to be exactly the same as it was before being rotated
The given wheel has 6 pairs of similar in-line spokes such that there are a total of 12 spokes
The wheel looks the same each time the next spoke moves to the position of the previous spoke
Therefore, the number of times the wheel looks exactly the same while turning 360° is 12 times
Therefore, the order of rotational symmetry of the wheel = 12.
