Question

14

DEF is a dilation of ABC with center (0,0). What is the scale factor?
3
1/2
1/3
1/4

Answer 1

that is a 1/3 dialation, becuase you can estimate the base of the bigger triangle to be around 12 and the base of the smaller triangle is 4, and that would be a fraction that is something like 4/12 which happens to be equal to 1/3.
