alleryWhich symmetry applies to an object that looks unchanged when turned about a fixed point?
AReflectional
BTranslational
CRotational
DHelical
Answer & Solution
Correct answer: C. Rotational
1. Turning an object about a fixed point is called a rotation.
2. If the shape looks the same afterwards, it has rotational symmetry.
3. Reflectional symmetry is mirroring, translational is sliding and scale is resizing.
