List the alphabets having rotational symmetry and reflection symmetry, and also list the orders in rotational symmetry as well as reflections symmetry.
Identify the alphabets having symmetry:
Alphabets having a reflection symmetry about a vertical mirror are
Alphabets having a reflection symmetry about a horizontal mirror are
Alphabets having both horizontal and vertical mirrors are
Alphabet having both reflection symmetry as well as rotation symmetry is
If the alphabets are rotated by degree about particular axes, they remain the same.
Therefore order of is
Hence, the list of symmetry of alphabets is identified.
