Randee draws these two triangles with length given in centimeters. What scale factor does she use to create the copy on the right from the original on the left?
Options:
1 1/3
2
1/2
1 2/3
To determine the scale factor, we need to compare the corresponding sides of the two triangles.
Let's denote the original triangle's side lengths as a, b, and c, and the corresponding side lengths of the copy as A, B, and C.
From the given diagram, we can see that side a corresponds to side A, side b corresponds to side B, and side c corresponds to side C.
Comparing the lengths of these corresponding sides, we have:
A/a = 2
B/b = 2
C/c = 2
Since all the corresponding side ratios are the same and equal to 2, we can conclude that the scale factor Randee used to create the copy on the right from the original on the left is 2. Therefore, the correct option is 2.
