Answer:
C.
Folding a regular hexagon along a line that bisects two vertex angles (these angles will be opposite each other) will display reflectional symmetry.
Another option is to fold it along a line that connects the midpoints of opposite sides.
Any shape that can be separated into two matching segments by a single line has reflectional symmetry.
Explanation:
Answer: If we fold the regular hexagon along the line joining any vertex to the midpoint of the other side or any two midpoints of the adjacent side or a line that bisects two vertex angles, then the regular hexagon has the reflectional symmetry.
