I think "isometries" and "rigid transformation" are two different names for the same thing. Look for "isometry" on wikipedia.
The identity transformation.
Because the glide reflection is a combination of two isometries, it is also an isometry.
Rotations, reflections, and translations are all isometries while a dilation isn't because it doesn't preserve distance
Reflecting
These are transformations that do not change the shape or size, only its location (translation) or orientation (rotation).
Rigid transformations, such as translations, reflections, and rotations, preserve the length, angle measures, and parallelism of geometric figures. By applying a combination of these transformations to two given figures, if the transformed figures coincide, then the original figures are congruent. This is because if two figures can be superimposed perfectly using rigid transformations, then their corresponding sides and angles have the same measures, establishing congruency.
The identity transformation.
They can alter the location or orientation of the figures but do not affect their shape or size.
Preservation of Length
Reflections, translations, and rotations are considered rigid motions because they preserve the size and shape of the original figure. These transformations do not distort the object in any way, maintaining the distances between points and angles within the figure. As a result, the object's properties such as perimeter, area, and angles remain unchanged after undergoing these transformations.
Yes, that is correct.
Because the glide reflection is a combination of two isometries, it is also an isometry.
The properties depend on what the transformations are.

no, Angelic Layer doesn't have transformations
Transformations - opera - was created in 1973.
Conditions on Transformations was created in 1973.
