  • 9. What is Rotational symmetry ?An image has Rotational Symmetry if there is acentre point aroundwhich the object is turned a certain number ofdegrees and the objectstill looks the same, ie it matches itself a number oftimes while it is being rotated Since this triangle will match itself 3 times as it is rotated it is said to have rotational symmetry of Order 3.
  • 10. Since all the toppings are  placed so evenly, this pizza has rotational symmetry of Order 6.This flowerhas rotationalsymmetry ofOrder 5 sinceit matchesitself 5 times..
