To solve the problem of indicating the corresponding sides and angles for each congruence statement, we need to match the vertices of the triangles in the given congruence statements. The order of the vertices in the congruence statement indicates which parts correspond to each other.

Problem Breakdown and Solution:



#### 1) \( \Delta XYZ \cong \Delta KLJ \)

- Vertices: \( X \leftrightarrow K \), \( Y \leftrightarrow L \), \( Z \leftrightarrow J \)
- Corresponding Sides:
- \( XY \leftrightarrow KL \)
- \( YZ \leftrightarrow LJ \)
- \( ZX \leftrightarrow JK \)
- Corresponding Angles:
- \( \angle X \leftrightarrow \angle K \)
- \( \angle Y \leftrightarrow \angle L \)
- \( \angle Z \leftrightarrow \angle J \)

#### 2) \( \Delta PQR \cong \Delta TSR \)

- Vertices: \( P \leftrightarrow T \), \( Q \leftrightarrow S \), \( R \leftrightarrow R \)
- Corresponding Sides:
- \( PQ \leftrightarrow TS \)
- \( QR \leftrightarrow SR \)
- \( RP \leftrightarrow RT \)
- Corresponding Angles:
- \( \angle P \leftrightarrow \angle T \)
- \( \angle Q \leftrightarrow \angle S \)
- \( \angle R \leftrightarrow \angle R \)

#### 3) \( \Delta UVW \cong \Delta DEF \)

- Vertices: \( U \leftrightarrow D \), \( V \leftrightarrow E \), \( W \leftrightarrow F \)
- Corresponding Sides:
- \( UV \leftrightarrow DE \)
- \( VW \leftrightarrow EF \)
- \( WU \leftrightarrow FD \)
- Corresponding Angles:
- \( \angle U \leftrightarrow \angle D \)
- \( \angle V \leftrightarrow \angle E \)
- \( \angle W \leftrightarrow \angle F \)

#### 4) \( \Delta RST \cong \Delta SRU \)

- Vertices: \( R \leftrightarrow S \), \( S \leftrightarrow R \), \( T \leftrightarrow U \)
- Corresponding Sides:
- \( RS \leftrightarrow SR \)
- \( ST \leftrightarrow RU \)
- \( TR \leftrightarrow US \)
- Corresponding Angles:
- \( \angle R \leftrightarrow \angle S \)
- \( \angle S \leftrightarrow \angle R \)
- \( \angle T \leftrightarrow \angle U \)

#### 5) \( \Delta VWX \cong \Delta YZX \)

- Vertices: \( V \leftrightarrow Y \), \( W \leftrightarrow Z \), \( X \leftrightarrow X \)
- Corresponding Sides:
- \( VW \leftrightarrow YZ \)
- \( WX \leftrightarrow ZX \)
- \( XV \leftrightarrow XY \)
- Corresponding Angles:
- \( \angle V \leftrightarrow \angle Y \)
- \( \angle W \leftrightarrow \angle Z \)
- \( \angle X \leftrightarrow \angle X \)

#### 6) \( \Delta ABC \cong \Delta UVT \)

- Vertices: \( A \leftrightarrow U \), \( B \leftrightarrow V \), \( C \leftrightarrow T \)
- Corresponding Sides:
- \( AB \leftrightarrow UV \)
- \( BC \leftrightarrow VT \)
- \( CA \leftrightarrow TU \)
- Corresponding Angles:
- \( \angle A \leftrightarrow \angle U \)
- \( \angle B \leftrightarrow \angle V \)
- \( \angle C \leftrightarrow \angle T \)

Final Answer:


\[
\boxed{
\begin{array}{ll}
1) & \text{Sides: } XY \leftrightarrow KL, YZ \leftrightarrow LJ, ZX \leftrightarrow JK \\
& \text{Angles: } \angle X \leftrightarrow \angle K, \angle Y \leftrightarrow \angle L, \angle Z \leftrightarrow \angle J \\
2) & \text{Sides: } PQ \leftrightarrow TS, QR \leftrightarrow SR, RP \leftrightarrow RT \\
& \text{Angles: } \angle P \leftrightarrow \angle T, \angle Q \leftrightarrow \angle S, \angle R \leftrightarrow \angle R \\
3) & \text{Sides: } UV \leftrightarrow DE, VW \leftrightarrow EF, WU \leftrightarrow FD \\
& \text{Angles: } \angle U \leftrightarrow \angle D, \angle V \leftrightarrow \angle E, \angle W \leftrightarrow \angle F \\
4) & \text{Sides: } RS \leftrightarrow SR, ST \leftrightarrow RU, TR \leftrightarrow US \\
& \text{Angles: } \angle R \leftrightarrow \angle S, \angle S \leftrightarrow \angle R, \angle T \leftrightarrow \angle U \\
5) & \text{Sides: } VW \leftrightarrow YZ, WX \leftrightarrow ZX, XV \leftrightarrow XY \\
& \text{Angles: } \angle V \leftrightarrow \angle Y, \angle W \leftrightarrow \angle Z, \angle X \leftrightarrow \angle X \\
6) & \text{Sides: } AB \leftrightarrow UV, BC \leftrightarrow VT, CA \leftrightarrow TU \\
& \text{Angles: } \angle A \leftrightarrow \angle U, \angle B \leftrightarrow \angle V, \angle C \leftrightarrow \angle T \\
\end{array}
}
