To find the scale factor from the smaller triangle to the larger triangle, you can divide the side length of the larger triangle by the side length of the smaller triangle.
Given:
- Side length of the small triangle = 23
- Side length of the big triangle = 66.7
The scale factor (SF) can be calculated as follows:
\[ SF = \frac{\text{Side length of big triangle}}{\text{Side length of small triangle}} = \frac{66.7}{23} \]
Calculating the division:
\[ SF = 2.91 \text{ (approximately)} \]
Therefore, the scale factor to go from the triangle on the left (small triangle) to the triangle on the right (big triangle) is approximately 2.91.
