Symmetric refers to a property where an object or shape is identical on both sides of a dividing line or around a central point. For example, a circle is symmetric because it looks the same from any angle, while a square has symmetry along its diagonals and midlines. In nature and art, symmetry is often associated with beauty and balance. Many living organisms, like butterflies, exhibit bilateral symmetry, meaning their left and right sides mirror each other. This concept is not only important in mathematics but also in design and architecture, where symmetry can create visually appealing structures.
