Question
### Which angle is congruent to ∠8? Select all that apply.

The diagram provided features two parallel lines, \( e \) and \( f \), intersected by a transversal \( g \). The points of intersection form eight angles, labeled as follows:

- On the upper line \( e \):
  - ∠1 and ∠2 above the line \( e \)
  - ∠3 and ∠4 below the line \( e \)
  
- On the lower line \( f \):
  - ∠5 and ∠6 above the line \( f \)
  - ∠7 and ∠8 below the line \( f \)

The question requires identifying all the angles congruent to ∠8.

### Answer Choices
- A. ∠1
- B. ∠2
- C. ∠3
- D. ∠4

To determine congruent angles, consider the following relationships between angles formed by parallel lines and a transversal:

- Corresponding Angles
- Alternate Interior Angles
- Alternate Exterior Angles
- Consecutive Interior Angles

### Explanation

∠8 is located below line \( f \) and to the right of the transversal \( g \).

- **Alternate Interior Angles**: These are angles on opposite sides of the transversal and inside the two parallel lines. ∠8 and ∠5 are alternate interior angles.
- **Corresponding Angles**: These are angles in matching corners when two lines are crossed by another line (the transversal). ∠8 and ∠4 are corresponding angles.
- **Alternate Exterior Angles**: Not applicable here for ∠8.
- **Consecutive Interior Angles**: Not applicable here for ∠8.

Therefore, angles congruent to ∠8 are:

- ∠4 (according to the corresponding angles postulate)

### Conclusion
Select the following:
- D. ∠4
