To determine the scale factor between the two triangles in the image:

We are given two triangles:
1. The left triangle has side lengths of 7 and 7.
2. The right triangle has side lengths of \( \frac{7}{3} \) and \( \frac{7}{3} \).

### Finding the scale factor:
The scale factor is the ratio of the corresponding sides of the two triangles. Let's compare the corresponding sides:

\[
\text{Scale factor} = \frac{\text{Side length of the right triangle}}{\text{Side length of the left triangle}}
\]

For the sides with lengths 7 on the left triangle and \( \frac{7}{3} \) on the right triangle:

\[
\text{Scale factor} = \frac{\frac{7}{3}}{7} = \frac{7}{3} \times \frac{1}{7} = \frac{1}{3}
\]

Thus, the scale factor is **\( \frac{1}{3} \)**, meaning the right triangle is scaled down by a factor of 1/3 compared to the left triangle.

**Tip:** When comparing similar triangles, always check if their angles are congruent before determining the scale factor based on side lengths.

The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
