alleryA solid object with reflection symmetry has what in place of a line of symmetry?
AA point of symmetry
BA plane of symmetry
CA curve of symmetry
DA ring of symmetry
Answer & Solution
Correct answer: B. A plane of symmetry
1. In two dimensions a figure is mirrored across a line or axis.
2. In three dimensions the mirror becomes a flat surface, called a plane of symmetry.
3. Points, curves and rings are not mirrors, so they do not define reflection symmetry.
