The three basic transformations are
(i) Translation
(ii) rotation and
(iii) Scaling.
Translation refers to the shifting of a point to some other place, whose distance with regard to the present point is
known. Rotation as the name suggests is to rotate a point about an axis. The axis can be any of the coordinates or simply any other specified line also. Scaling is the concept of increasing (or decreasing) the size of a picture. (in one or in either directions. When it is done in both directions, the increase or decrease in both directions need not be same) To change the size of the picture, we increase or decrease the distance between the end points of the picture and also change the intermediate points are per requirements.
