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.
