To determine which polygons (triangles in this case) are similar, we need to check if they have the same shape, which means their corresponding angles are equal.

**Let's examine each triangle:**

1. **Triangle 1:**
   - Angles: \(60^\circ, 110^\circ, 10^\circ\)

2. **Triangle 2:**
   - Angles: \(60^\circ, 30^\circ, 90^\circ\)

3. **Triangle 3:**
   - Angles: \(80^\circ, 10^\circ, 90^\circ\)

4. **Triangle 4:**
   - Angles: \(60^\circ, 10^\circ, 110^\circ\)

**Identifying Similar Triangles:**

Triangles are similar if all their corresponding angles are equal. Let's compare:

- **Triangle 1 and Triangle 4** both have angles: \(60^\circ, 10^\circ, 110^\circ\). Therefore, these two triangles are similar.
- The other triangles do not have the same set of angles, so they are not similar to each other or to Triangle 1 and Triangle 4.

**Conclusion:**
Triangles 1 and 4 are similar.
