For a figure or object that has rotational symmetry, the fixed point around which the rotation occurs is called the centre of rotation. Example: the centre of rotation of a windmill in the centre of the windmill from which its blades originate. Click here to understand what is rotationand center of rotation in detail.
For a figure or object that has rotational symmetry, the angle of turning during rotation is called the angle of rotation. Example: when a square is rotated by 90 degrees, it appears the same after rotation. So, the angle of rotation for a square is 90 degrees. In the same way, a regular hexagon has an angle of symmetry as 60 degrees, a regular pen...
The number of positions in which a figure can be rotated and still appears exactly as it did before the rotation, is called the order of symmetry. For example, a star can be rotated 5 times along its tip and look at the same every time. Hence, its order of symmetry is 5. If we consider the order of symmetry for regular hexagon it is equal to 6, sin...
There are many capital letters of English alphabets which has symmetry when they are rotated clockwise or anticlockwise about an axis. Some of them are: Z, H, S, N and O. When these letters are rotated 180 degrees clockwise or anticlockwise the letters appears to be same. Also, read:

See examples of rotational symmetry in letters, figures and symbols and test your knowledge with a quiz.
Learn what rotational symmetry is and how to find its order and angle of rotation for different geometrical shapes. See examples of rotational symmetry in objects and shapes and practice questions on rotational symmetry.
To calculate the order of rotational symmetry of a shape, you need to locate the centre of the shape. If the polygon has an even number of sides, this can be done by joining the diagonals. If the polygon has an odd number of sides, this can be done by joining each vertex to the midpoint of the opposing side.
