alleryAn object has reflectional symmetry if a line divides it into two pieces that are what?
AMirror images
BSmaller copies
CRotated copies
DShifted copies
Answer & Solution
Correct answer: A. Mirror images
1. Reflectional symmetry is also called line or mirror symmetry.
2. A line splits the object into two pieces, and each piece is the mirror image of the other.
3. Smaller, rotated or shifted copies describe scaling, rotation and translation instead.
