Rotational symmetry occurs when an object can be rotated around a central point and still look the same at certain angles. For example, a star with five points has rotational symmetry because it appears unchanged when rotated by 72 degrees. The number of times an object matches its original shape during a full 360-degree rotation is called its order of symmetry. Many everyday objects exhibit rotational symmetry, such as flowers, wheels, and geometric shapes. Understanding this concept helps in various fields, including art, design, and mathematics, as it allows for the creation of visually appealing and balanced compositions.
