Question1.
Scale Factor:

Studdy Solution
Calculate the scale factor using the ratio of the corresponding sides:
$$\text{Scale Factor} = \frac{\text{Side length of Image}}{\text{Side length of Pre-image}}$$
$$\text{Scale Factor} = \frac{2}{1} = 2$$
The scale factor from the pre-image triangle to the image triangle is:
$$\boxed{2}$$
