To determine the scale factor used to create the copy on the right from the original on the left, we need to compare the corresponding side lengths of the two triangles.
Since the options provided are not clear, please provide the side lengths of the two triangles so that we can calculate the scale factor accurately.
To determine the scale factor used to create the copy on the right from the original on the left, we can compare the corresponding side lengths of the two triangles.
Let's label the side lengths of the original triangle as a, b, and c, and the corresponding side lengths of the copy triangle as a', b', and c'.
Looking at the given options:
- Option 12: This is not a valid scale factor as it does not correspond to the relationship between the side lengths.
- Option 1/2: This is a possible scale factor if it relationship between the side lengths is maintained.
- Option 123: This is not a valid scale factor as it does not correspond to the relationship between the side lengths.
- Option 2: This is not a valid scale factor as it does not correspond to the relationship between the side lengths.
- Option 113: This is not a valid scale factor as it does not correspond to the relationship between the side lengths.
Comparing the side lengths of the two triangles, we find that the copy triangle has side lengths that are half the length of the original triangle. Therefore, the correct scale factor used to create the copy on the right from the original on the left is 1/2.
So, the correct answer is option Start Fraction 1 over 2 End Fraction.
