What is Symmetry?
Symmetry is when an object has two or more equal sides when split in half or in smaller pieces.
The tiger has 1 line of 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.

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..
