A four-sided figure, such as a rectangle or a square, can have different orders of symmetry. A square has an order of symmetry of 8, as it can be folded along lines of symmetry in multiple ways (four lines through the midpoints of opposite sides and two diagonals). A rectangle has an order of symmetry of 4, with two lines through the midpoints of opposite sides and two diagonals. In general, the order of symmetry refers to the number of times a shape can be mapped onto itself during a full rotation (360 degrees).
