Question

Show that the following letters of English alphabet
have rotational symmetry of order 2.
(a)I
(b) N
(c) s​

Answer 1

Answer:

All the given alphabet (I, N and S) when rotated 360° from their initial positions, appear same two times. All the three alphabets appear same if rotated by an angle of 180° and 360° from its initial position (at 0°). Thus they show rational symmetry of order 2.
