The number of times an object looks the same in one complete turn is called the _________.

• A. angle of rotation
• B. centre of rotation
• C. direction of rotation
• D. order of rotational symmetry

Answer 1

The correct option is D order of rotational symmetry

Number of times an object looks the same in one complete turn is called the order of rotational symmetry.

For example, consider the figure below:


In the next turn, we will get the orginal triangle.
Here, the order of rotational symmetry is 3.
