Answer :

Answer:

Step-by-step explanation:

The triangles are not similar. Looking at the diagram, triangle STU is smaller than triangle PQR. If they are similar, it would mean that

ST/PQ = TU/QR = SU/PR

This means that there would be a scale factor. Substituting, the values, it becomes

ST/PQ = 7/9 = 0.78

TU/QR = 10/15 = 0.67

SU/PR = 8/12 = 0.67

Therefore, since

ST/PQ ≠ TU/QR ≠ SU/PR

The triangles are not similar.
