Symmetrical shapes are figures that can be divided into two identical halves. When a line is drawn through the center, each side mirrors the other. Common examples of symmetrical shapes include circles, squares, and triangles. These shapes are often found in nature, art, and architecture, providing balance and harmony. Symmetry can be classified into two main types: reflective and rotational. Reflective symmetry occurs when one half is a mirror image of the other, while rotational symmetry involves shapes that look the same after being rotated around a central point. Understanding symmetrical shapes is essential in fields like mathematics and design.
