Answer : True
To find scale factor you divide the sides of the original shape by the sides altered shape. In this case the original shape is the one on the left and the altered shape is the one on the right.
So in this problem you would divide the side on the left 36, by the side on the right, 18
36 / 18 = 2
Since the shape was made smaller you would find the reciprocal of 2, which is 1/2.
