Solution

$(1) Z - No - 0 - Yes - 2 (2) H - Yes - 2 - Yes - 2 It has two line of symmetry . as it can be cut horizontally as well as vertically . To give two same figure . It can be rotate 180 ° clockwise and also 180 ° anticlockwise to provide exact alphqabet . So it has two rotational symmetry . (3) E - Yes - 1 - Yes - 1 It has one line of symmetry . as it can be cut horizontally . it can be rotate 360 ° to get exact alphabet . so, it has one rotational symmetry . (4) I - Yes - 2 - Yes - 2 It has two line of symmetry . as it can be cut horizontally as well as vertically . To give two same figure . It can be rotate 180 ° clockwise and also 180 ° anticlockwise to provide exact alphqabet . So it has two rotational symmetry .$
