Concept

Order of Symmetry

For a figure that has rotational symmetry, the number of times the figure looks the same when rotated by an angle less than or equal to

36 0^{\circ},

is called the order of symmetry.

Consider the examples in the applet. A square has rotational symmetry of order

4 .

An equilateral triangle has rotational symmetry of order

3,

and the digit

0

has an order of symmetry of 2.
