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?

[the measurements are 30 in, 20 in, 36 in, 15 in, 18, in, and 10 in]
To determine the scale factor, we can compare the corresponding sides of the two triangles.
For the original triangle:
- The length of the longest side is 36 in.
- The length of the medium side is 30 in.
- The length of the shortest side is 20 in.
For the copied triangle:
- The length of the longest side is 18 in.
- The length of the medium side is 15 in.
- The length of the shortest side is 10 in.
To find the scale factor, we can divide the lengths of the corresponding sides:
Scale factor for the longest side: 18/36 = 1/2
Scale factor for the medium side: 15/30 = 1/2
Scale factor for the shortest side: 10/20 = 1/2
Therefore, the scale factor Randee uses is 1/2.
