Rotational Symmetry
Rotational symmetry is the property of the figure due to which its shape remains the same on rotation as compared to the original shape. These figures have an axis of symmetry and are said to possess rotational symmetry. Rotational symmetry can be found using many ways. The easiest way is to start rotating the object from 0° to 360°. If the shape of an object during rotation coincides with its original shape then it is said to possess rotational symmetry at that angle of rotation. For example, a Square possesses rotational symmetry when rotated through angles that are multiples of 90°, a circle possesses rotational symmetry at all angles of rotation whereas a triangle possesses no rotational symmetry.
Rotation
In real life, we know that the Earth rotates on its own axis and the moon also rotates on its axis. But what basically rotation is? Also, geometry deals with four basic types of transformations that are Rotation, Reflection, Translation, and Resizing. In this article, we shall read about the fundamental concept of rotation.
