Lines of Symmetry in a Rhombus

A rhombus is a quadrilateral with all sides of equal length. It also has opposite sides that are parallel to each other. In addition to these properties, a rhombus also possesses lines of symmetry.

Definition of a Line of Symmetry
A line of symmetry is a line that divides a figure into two halves that are mirror images of each other. In other words, if a figure can be folded along a line of symmetry, both halves will coincide perfectly.

Identifying Lines of Symmetry in a Rhombus
To determine the number of lines of symmetry in a rhombus, let's examine its properties:

1. Opposite Sides: A rhombus has opposite sides that are parallel to each other. This means that if we draw a line connecting the midpoints of these opposite sides, it will be a line of symmetry. There are two such lines in a rhombus.

2. Diagonals: A rhombus has two diagonals that intersect each other at right angles. The diagonals of a rhombus are not lines of symmetry, as they do not divide the figure into mirror images.

Total Number of Lines of Symmetry
Considering the properties mentioned above, we can conclude that a rhombus has two lines of symmetry.

Therefore, the correct answer to the question is option 'B' - 2.

In rhombus there is 2diagonals . so it have 2only.
