How can a regular hexagon be folded to show that it has reflectional symmetry?
fold the hexagon along a line from a vertex to the midpoint of an opposite side.
fold the hexagon along a line connecting the two midpoints of adjacent sides
fold the hexagon along a line that bisects two vertex angles.
fold the hexagon along a line that creates a right angle at a vertex

The figure below shows a line graph and two shaded triangles that are similar:

Step-by-step explanation:

it will fold and look the same

c. Fold the hexagon along a line that bisects two vertex angles.

Step-by-step explanation:

Reflectional symmetry also means the mirror symmetry. This occurs when a shape is divided by a line in halves, and each half is a reflection of the other half.

So, the regular hexagon must be folded like the following way to show that it has reflectional symmetry -

Fold the hexagon along a line that bisects two vertex angles.

if you need just tell me and i will come to the rescue.
