Which of the following transformation techniques is responsible for altering (either enlarging it or diminishing it) the size of the object?
Translation
Rotation
Scaling
None of the above
Correct Answer :
C. Scaling
Scaling is be used to increase or decrease which is reduce the size of object. Scaling subjects to the co-ordinate points of the original object is to be changed. The scaling factor determines whether the size of the object is to be increased or decreased.
