Answer 1

These are my modest thoughts on the subject

A) A translation have to do with mapping from one system of coordinates onto another. For example a rectangular grid projected unto a spherical, cylindrical or a rectangular surface under a different plane then the original.

B) I agree

C) Both of them are projections from one surface onto another.

D) Yes. Some angles and proportions will be preserved as well as the relations between different aspects of the original object and projected object. If you are standing before a mirror it may distort the original image if its surface is not flat, however the relationship will be preserved and hopefully your face will be above your feet ;-).

I hope it helps. Let me know.
