To find the scale factor, we need to determine the ratio between the corresponding sides of the two triangles. The corresponding sides are 10 in. and 20 in., 15 in. and 30 in., and 18 in. and 36 in.
The ratio between the corresponding sides is:
10 in. / 20 in. = 1/2
15 in. / 30 in. = 1/2
18 in. / 36 in. = 1/2
Therefore, the scale factor is 1/2.
