The fourth one is a rigid transformation because it is a rotation
The fifth one is a rigid transformation because it is a rotation
The sixth one is not a rigid transformation because the size of the original image changes
The seventh one is not a rigid transformation because the size of the original image changes
The eighth one is a rigid transformation, because it is a reflection about the y axis
The ninth one is a rigid transformation because it is a translation
