(a)
The angle R of triangle PQR is congruent to the angle U of triangle STU. So
[tex]\angle R\cong\angle U[/tex]
(b)
The angle H of triangle GHJ is congruent to angle Q of triangle PQR and angle Q of triangle PQR is congruent to angle T of triangle STU, which means
[tex]\begin{gathered} \angle H\cong\angle Q \\ \angle Q\cong\angle T \end{gathered}[/tex]
So,
[tex]\angle H\cong\angle T[/tex]
(c)
The side QR of triangle PQR is congruent to the side TU of triangle STU. So
[tex]QR\cong TU[/tex]
(d)
The side JG of triangle GHj is congruent to side RP of triangle PQR and side RP of triangle PQR is congruent to side US of triangle STU. So
[tex]JG\cong US[/tex]
