Chapter 12, Problem 6CA

To determine

To find: The Figure that has the rotational symmetry and select all that apply.

Answer to Problem 6CA

The definition the rotational symmetry shows that all given figure has the rotational symmetry.

Explanation of Solution

Given:

The given diagram is shown in Figure 1

  

Figure 1

Calculation:

The figure has the rotational symmetry when the figure can be mapped on itself by the rotation of $180°$ or less than it about the centre of the figure and the point is called the centre of symmetry.

Thus, from the above definition the rotational symmetry shows that all given figure has the rotational symmetry.
