**Labeling Angles: Understanding Angle Relationships**

In this exercise, you are provided with a geometrical diagram where two parallel lines, \( f \parallel g \), are intersected by a transversal line. The goal is to label each missing angle in the diagram using the given information and your knowledge of angle relationships.

### Diagram Overview:

- **Label Definitions:**
  - Parallel lines: \( f \parallel g \)
  - Transversal line intersecting both \( f \) and \( g \)
  - Given angle: \( 85^\circ \)

- **Angles to Identify:**
  - Angle 1
  - Angle 2
  - Angle 3
  - Angle 4
  - Angle 5
  - Angle 6
  - Angle 7
  - Angle 8

### Utilizing Angle Relationships:

1. **Corresponding Angles:**
   - When a transversal crosses parallel lines, the pairs of corresponding angles are equal.
   - Here, angle 2 corresponds to the given \( 85^\circ \), meaning angle 2 is also \( 85^\circ \).

2. **Alternate Interior Angles:**
   - Alternate interior angles are equal when the lines are parallel.
   - Thus, angle 4 is also \( 85^\circ \).

3. **Vertically Opposite Angles:**
   - Vertically opposite angles are equal.
   - Therefore, angle 6 is \( 85^\circ \).

4. **Supplementary Angles:**
   - Adjacent angles that form a straight line (linear pairs) are supplementary, meaning they add up to \( 180^\circ \).
   - Angle 3 (adjacent to \( 85^\circ \)) would be \( 180^\circ - 85^\circ = 95^\circ \).
   - Angle 1 (adjacent to angle 3) would also be \( 95^\circ \).
   - Angle 7 (vertically opposite to angle 3) would also be \( 95^\circ \).
   - Angle 5 (vertically opposite to the given \( 85^\circ \)) is \( 95^\circ \).
   - Angle 8 (corresponding to angle 7) is \( 95^\circ \).

### Conclusion:

By using the relationships between angles, we determined the following:

- Angle 1: \( 95^\circ \
