Based on the image provided, you are working on a geometry problem involving pairs of angles formed by parallel lines and a transversal. Here are the answers based on the typical types of angles formed:

1. Corresponding Angles: Corresponding angles occur when two parallel lines are crossed by a transversal, and they are on the same side of the transversal and in corresponding positions.

   • Corresponding angle pairs:
     1. $\angle 1$ and $\angle 5$
     2. $\angle 2$ and $\angle 6$
     3. $\angle 3$ and $\angle 7$
     4. $\angle 4$ and $\angle 8$

2. Alternate Interior Angles: Alternate interior angles are inside the parallel lines and on opposite sides of the transversal.

   • Alternate interior angle pairs:
     1. $\angle 3$ and $\angle 6$
     2. $\angle 4$ and $\angle 5$

3. Alternate Exterior Angles: Alternate exterior angles are outside the parallel lines and on opposite sides of the transversal.

   • Alternate exterior angle pairs:
     1. $\angle 1$ and $\angle 8$
     2. $\angle 2$ and $\angle 7$

Would you like any further clarification or detailed explanations on the types of angles?

Here are five follow-up questions to help you understand more:

1. How do you identify corresponding angles in more complex diagrams?
2. What are the properties of alternate interior angles?
3. Can alternate exterior angles ever be supplementary?
4. How do same-side interior angles differ from alternate interior angles?
5. What happens if the lines are not parallel—do these angle relationships still hold?

Tip: Always check whether lines are parallel before applying angle rules such as corresponding or alternate angles.
