Two triangles are given. Which statement accurately describes the relationship between the two triangles? 

The image presents a multiple-choice question related to triangle similarity and congruence. The options are as follows:

1. A circle indicating a choice, followed by "△UVW ~ △XZY"
2. A circle indicating a choice, followed by "△UVW ≅ △XZY"
3. A circle indicating a choice, followed by "△UVW ~ △XYZ"
4. A circle indicating a choice, followed by "△UVW ≅ △XYZ"

Each option involves two triangles (△UVW and △XZY/△XYZ) with the symbols "~" representing similarity and "≅" representing congruence. The task is to choose the correct relationship between the triangles.

The image displays two triangles labeled as \( \triangle UWV \) and \( \triangle XYZ \).

### Details of Each Triangle:

1. **Triangle UWV**:
   - **Sides**: 
     - \( UW \) and \( WV \) have a single tick mark, indicating they are of equal length.
     - \( UV \) has a different length, indicated by a unique tick mark.
   - **Angles**:
     - The angle at vertex \( U \) is marked with a single arc.
     - The angle at vertex \( V \) also has a single arc, indicating it is equal to the angle at \( U \).
     - The angle at vertex \( W \) is not marked, implying it differs from the angles at \( U \) and \( V \).

2. **Triangle XYZ**:
   - **Sides**:
     - \( XZ \) and \( ZY \) have a single tick mark, indicating they are of equal length.
     - \( XY \) has a different length, denoted by a unique tick mark.
   - **Angles**:
     - The angle at vertex \( X \) is marked with a single arc.
     - The angle at vertex \( Y \) also has a single arc, indicating it is equal to the angle at \( X \).
     - The angle at vertex \( Z \) is not marked, implying it differs from the angles at \( X \) and \( Y \).

### Geometric Observations:

- Both triangles are isosceles triangles, demonstrated by the pairs of equal sides and angles.
- The congruent angles in each triangle suggest similarity in their shape, although they may differ in size.
- This image is useful for illustrating properties of isosceles triangles in geometry.
