## Lines of Symmetry in a Rhombus

A rhombus is characterized by four equal sides and opposite sides that are parallel. When we fold a rhombus along an imaginary line, the resulting halves are perfectly symmetrical. This line is known as the line of symmetry in a rhombus. In a rhombus, there are two lines of symmetry, which are represented by its diagonals. Folding the rhombus along either diagonal yields two identical halves, with their edges and corners coinciding. The diagram below illustrates these two lines of symmetry in a rhombus.

In the diagram, ABCD represents a rhombus, where the diagonals AC and BD act as the two lines of symmetry.

## Rotational Symmetry in a Rhombus

Apart from lines of symmetry, a rhombus also exhibits rotational symmetry. Rotational symmetry refers to a shape or image that appears identical to its original form after a full rotation of 360 degrees. In the case of a rhombus, it possesses rotational symmetry of order 2. This means that when a rhombus is rotated by 360 degrees, it aligns with itself twice, confirming the existence of rotational symmetry. The angle of rotation for a rhombus is 180 degrees. The following image demonstrates the rotational symmetry of a rhombus.

By observing the images, we can conclude that a rhombus fits onto itself twice in a full rotation of 360 degrees, indicating the order of rotational symmetry as 2.

## Lines of Symmetry in a Non-Square Rhombus

It’s important to note that a rhombus comes in different variations. A square is a special type of rhombus with all internal angles measuring 90 degrees. However, a non-square rhombus, also known simply as a rhombus, differs from a square in terms of its internal angles. Unlike a square, a non-square rhombus does not have all internal angles equal to 90 degrees.

A non-square rhombus exhibits two lines of symmetry, just like a square. However, a square possesses four lines of symmetry. The lines of symmetry in a square are drawn through its vertical axis, horizontal axis, and two diagonals. In contrast, the lines of symmetry in a non-square rhombus are drawn solely through its diagonals. The diagram below illustrates the lines of symmetry in both a square and a non-square rhombus.

As seen in the diagram, the square exhibits four lines of symmetry, while the non-square rhombus showcases two lines of symmetry, represented by its diagonals.
