The order of rotational symmetry of regular octagon is

Options

A. 7
B. 8
C. 10
D. 6

Answer

To find the order of rotational symmetry of a regular octagon, we can follow these steps:

### Step 1: Understand the Definition
The order of rotational symmetry of a shape is the number of times the shape fits onto itself during a full rotation of 360 degrees.

### Step 2: Identify the Shape
A regular octagon is a polygon with 8 equal sides and 8 equal angles.

### Step 3: Use the Formula
For a regular polygon, the order of rotational symmetry is equal to the number of sides (n) of the polygon.

### Step 4: Apply the Formula
Since an octagon has 8 sides, we can say:
- n = 8

### Step 5: Conclusion
Thus, the order of rotational symmetry of a regular octagon is 8.

### Final Answer
The order of rotational symmetry of a regular octagon is **8**.
