Solution

1 Z-No-0-Yes-22H-Yes-2-Yes-2It 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.3E-Yes-1-Yes-1It 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.4I-Yes-2-Yes-2It 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.
