Answer:
Yes the polygons are similar, MNOP is congruent to figure STUR, scale factor=1.5
Step-by-step explanation:
If two figures are similar, they don't have to be congruent, but their angles must be congruent respective to each one.
So the similarity statement is figure MNOP is congruent to figure STUR
The scale factor would be 1.5 because 4.5/3=1.5
