To find the scale factor between the two figures in the image, we need to compare the corresponding side lengths of the smaller and larger triangles.

The scale factor is the ratio of the side lengths of the larger triangle to the smaller triangle. Looking at the two figures, the black lines represent the smaller triangle, and the red lines represent the larger triangle.

By measuring the corresponding side lengths of the two triangles, we can compute the scale factor. Let's identify the relevant side lengths and proceed to calculate the scale factor.
