C. greater than
D. not equal
View Answer
Ans : D
Explanation: If Sxand Sy are not equal then scaling will occur but it will elongate or distort the picture
4. If scaling factors are less than _______, then the size of the object will be reduced.
A. 0
B. 1
C. 2
D. 3
View Answer
Ans : B
Explanation: If scaling factors are less than one, then the size of the object will be reduced.
