Rotational Symmetry All 2 dimensional shapes have some rotational symmetry. The degree of rotational symmetry that an object has is known as its order. Order 1 Order 2 Order 3 Order 4 For shapes that have “order 2” rotational symmetry or higher, a single centre of rotation can be located. For shapes that have only “order 1” rotational symmetry a centre of rotation can be found anywhere within it.
Rotational Symmetry The order of rotational symmetry that an object has is the number of times that it fits on to itself during a full rotation of Order 1
Rotational Symmetry Order Order 2 The order of rotational symmetry that an object has is the number of times that it fits on to itself during a full rotation of 360 0
Rotational Symmetry Order Order Order 3 The order of rotational symmetry that an object has is the number of times that it fits on to itself during a full rotation of 360 0
