You can transform △STU to △S'T'U' by translating it and then performing a dilation centered at the origin. So, △STU~△S'T'U'. Find the translation rule and the scale factor of the dilation.
Simplify the scale factor and write it as a proper fraction, improper fraction, or whole number.
Translation: (x,y)↦
