To determine the scale factor, we compare the lengths of corresponding sides in the two triangles. Looking at the longest side of the original triangle (left) and the corresponding side in the copy triangle (right), we see that the length of the longest side in the copy triangle is twice the length of the longest side in the original triangle.
Therefore, the scale factor is 2.
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?
