Symmetry is a concept that describes balance and harmony in shapes and forms. When an object is symmetrical, it means that one side is a mirror image of the other. For example, a butterfly has symmetrical wings, where each side looks the same. This balance can be found in nature, art, and even architecture, making things visually appealing. In mathematics, symmetry can be seen in geometric shapes like squares and circles. These shapes have specific lines or points where they can be divided into equal parts. Understanding symmetry helps us appreciate the beauty in nature, design, and mathematics, revealing patterns that are pleasing to the eye.
