Rotational symmetry of 2D shapes - Answers
1. The quadrilateral does not have rotational symmetry.
2. This is the completed table:
| Rotation | Applies to the figure? |
| Rotational symmetry of \(90^{\circ}\) about the origin | Yes/No |
| Rotational symmetry of \(180^{\circ}\) about the origin | Yes/No |
3. Of the choices, the circle has rotational symmetry about its center for magnitudes of \(7^{\circ}, 45^{\circ}\), \(90^{\circ}, 210^{\circ}\), and \(355^{\circ}\).
4. This is the completed table:
| Rotation | Applies to the figure? |
| Rotational symmetry of \(90^{\circ}\) about the origin | Yes/No |
| Rotational symmetry of \(180^{\circ}\) about the origin | Yes/No |
