To find the scale factor, we can compare the corresponding side lengths of the two triangles.
The corresponding side lengths from the left triangle to the right one are:
10 in. to 20 in. (doubled)
15 in. to 30 in. (doubled)
36 in. to 18 in. (halved)
So, the scale factor is 2.
Hence, the correct answer is 2.
10 in.
15 in.
36 in.
20 in.
18 in.
30 in.
Randee draws these two triangles with lengths given in centimeters. What scale factor does she use to create the copy on the right from the original on the left?
