Symmetry is a mathematical concept that describes a balanced and proportionate arrangement of elements. In mathematics, there are different types of symmetry, and it is often studied in geometry. Here are some key types of symmetry: 1. **Reflection Symmetry (Line Symmetry):** - A shape has reflection symmetry if there is a line (called the line of symmetry) such that one side of the line is a mirror image of the other. - For example, a square has four lines of symmetry, one along each side. 2. **Rotational Symmetry:** - A shape has rotational symmetry if it looks the same after a certain amount of rotation (less than a full turn). - The number of times a shape looks the same during a full turn is called the order of rotational symmetry. - For example, a circle has infinite rotational symmetry, as it looks the same at any angle of rotation. 3. **Point Symmetry:** - A shape has point symmetry if there is a point around which the shape can be rotated 180 degrees to map onto itself. - Some letters, like the letter "A," have point symmetry. 4. **Translational Symmetry:** - A shape has translational symmetry if it can be moved from one place to another without changing its overall shape. - Regular patterns, like a checkerboard, often exhibit translational symmetry. Understanding and identifying these types of symmetry can be important in geometry and other areas of mathematics.

nature.

5. Rotational symmetry: object
looks same at different
rotations.
Example: Windmill blades
create repeating pattern.

right sides mirror each
other.
Example: Human faces show
bilateral symmetry.
