What is Rotational symmetry ?: 

What is Rotational symmetry ? An image has Rotational Symmetry if there is a centre point around which the object is turned a certain number of degrees and the object still looks the same, ie it matches itself a number of times 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.

PowerPoint Presentation: 

Since all the toppings are  placed so evenly, this pizza has rotational symmetry of Order 6. This flower has rotational symmetry of Order 5 since it matches itself 5 times..
