2D Geometrical Transformations
Assumption: objects consist of points and lines. A point is represented by its Cartesian coordinates:
P-(x,y)
Geometrical Transformation :
Let (A, B) be a straight line segment between the points A and B.
Let T be a general 2D transformation.
T transforms (A, B) into another straight line segment (A', B'), where:
A'=TA and B'=TB
