A hexagon is a 6 sided polygon which has a 720° total of internal angles.
A regular hexagon has both reflective and rotation symmetry.
It has 6 rotational symmetries with an angle of 60°.
It has 6 reflection symmetries meaning it has 6 lines of axes.
It is easy to see if there is Reflection symmetry because one half of the whole is the reflection of the other half. In a regular hexagon, you can draw 6 lines across it and still have reflection symmetry.
In Rotational symmetry, the image is rotated around a central point and still looks the same. The regular hexagon is rotated 12 times at an angle of 60°.
