A shape has Rotational Symmetry when it still looks the same after some rotation (of less than one full turn). How many times it matches as we go once around is called the Order. Think of propeller blades (like below), it makes it easier. ... and there is also Order 5, 6, 7, and ... ... and Orders 9, 10, and so on.

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:
The recycle logo has an order of symmetry of 3.The paper windmill has an order of symmetry of 4.The triangle has an order of symmetry of 3.The Swastik symbol has an order of symmetry of 4.The roundabout road sign has an order of symmetry of 3.May 20, 2024 · What is Order of Rotational Symmetry? Order of Rotational Symmetry denotes how many times a shape aligns with its original position during a full 360-degree rotation. Which Letters Exhibit Rotational Symmetry? Various letters that exhibit Rotational Symmetry are Z, H, S, N and O.
How do you find the order of rotational symmetry? To find the order of rotational symmetry of a shape, identify the center of the shape, rotate the shape around its center, and count how many times the shape matches its original position in one full 360^{\circ} rotation.
Rotational symmetry of order n, also called n-fold rotational symmetry, or discrete rotational symmetry of the nth order, with respect to a particular point (in 2D) or axis (in 3D) means that rotation by an angle of (180°, 120°, 90°, 72°, 60°, 51 3⁄7 °, etc.) does not change the object.
Aug 3, 2023 · What is the order of rotational symmetry of a rhombus? The diagram shows the order of rotational symmetry when we try rotating a rhombus. Thus, a rhombus has a rotational symmetry of order 2. Similarly, alphabets or letters like H, I, N, S, and Z also possess rotational symmetry.

What is rotational symmetry of a shape?
Rotational symmetry is defined as a type of symmetry in which the image of a given shape is exactly identical to the original shape or image in a complete turn or a full angle rotation or 360° rotation. It exists when a shape is turned, and the shape is identical to the original.
