Symmetry refers to a property of an object or concept where it can be divided into two or more parts that are identical or mirror images of each other. This invariance under a transformation, such as reflection, rotation, or translation, is a fundamental concept across various disciplines. In geometry, symmetry is often described by the types of transformations that leave an object unchanged. Common types include reflectional symmetry, where an object can be folded along a line or plane to create two congruent halves, and rotational symmetry, where an object appears the same after being rotated by a certain angle around a central point.

The concept of symmetry extends beyond pure mathematics and geometry. In physics, symmetry principles play a crucial role in understanding the laws of nature. For instance, the conservation of energy is related to time-translation symmetry, and the conservation of momentum is linked to space-translation symmetry. In chemistry, molecular symmetry influences properties such as polarity and reactivity. In biology, symmetrical body plans are prevalent in many organisms, facilitating movement and sensory perception. The aesthetic appeal of symmetry is also widely recognized in art, architecture, and design, where balanced and harmonious compositions often employ symmetrical arrangements. The absence of symmetry is known as asymmetry.
