Hi, my wife is taking a course of mathmatics (she is a teacher), and this course is taken from a long distance. The University has a book on "Geometric Transformations" but there no suficient exercices, and who exist have no solutions.

As you are in the field i'd like to ask if you know any site or any book related because i only find introductions and informatic or programing related with the matter.

The program is:

Transformation introdution
Circunferencias
Transformation in euclidean plan

Thanks in advance,
