Question

the triangle on the right is a scaled copy of the triangle on the left. identify the scale factor. express your answer as a fraction in simplest form.

Explanation:

Step1: Recall the formula for scale factor

Scale factor \(=\frac{\text{Length of corresponding side in scaled copy}}{\text{Length of corresponding side in original figure}}\)

Step2: Substitute the values

Here, length of corresponding side in scaled copy \( = 11\), length of corresponding side in original figure \(=81\)
Scale factor \(=\frac{11}{81}\)

Answer:

\(\frac{11}{81}\)
