Question

We say that a figure has a rotational symmetry of more than 1 when __.

• A. When you rotate a figure for 90° and get the original figure
• B. When you rotate a figure for 180° and get the original figure
• C. When you rotate a figure for 270° and get the original figure
• D. When you rotate a figure for 360° and get the original figure

Answer 1

Answer: (A), (B), (C)

The correct options are
A

When you rotate a figure for 90° and get the original figure

B

When you rotate a figure for 180° and get the original figure

C

When you rotate a figure for 270° and get the original figure

During a ${360}^{\circ }$ rotation, if a figure looks exactly like the original figure at some angle less than ${360}^{\circ }$, then the figure is said to have rotational symmetry.

Any figure can be rotated by an angle of ${360}^{\circ }$ to look exactly the same. But, we say that an object has rotational symmetry if the order is more than 1.
