You correctly identified the corresponding sides. However, you identified the angles that are roughly in the same position with each other, though these are not corresponding angles. The information in the problem tells you that M and S are corresponding angles, and also that N and T are corresponding angles. The correct answer is $\displaystyle{M}{N}\leftrightarrow{S}{T}\usepackage{cmbright}\Huge\$ , $\displaystyle{N}{P}\leftrightarrow{T}{R}\usepackage{cmbright}\Huge\$ , $\displaystyle{M}{P}\leftrightarrow{S}{R}\usepackage{cmbright}\Huge\$ , and $\displaystyle\angle{P}\leftrightarrow\angle{R}\usepackage{cmbright}\Huge\$ .
