Angle pairs formed by parallel lines cut by a transversal.

It looks like you've uploaded an image of a worksheet titled "Angle Pairs Created by Parallel Lines Cut by a Transversal." The task is to identify each pair of angles in the diagrams and classify them as one of the following types:

- Corresponding Angles
- Alternate Interior Angles
- Alternate Exterior Angles
- Same-Side Interior Angles
- Same-Side Exterior Angles
- Vertical Angles

Each row contains three diagrams, and for each diagram, you need to label the angle pair based on its position relative to the parallel lines and the transversal.

Since I can't view images directly, I'll guide you through how to solve this type of problem step-by-step. If you describe the diagrams or list the angle pairs shown (e.g., "angle 1 and angle 5"), I can help you classify them.

But here’s a general explanation of the angle pairs formed when two parallel lines are cut by a transversal:

🔹 Key Definitions:

1. Corresponding Angles:
- Angles that are in the same relative position at each intersection.
- Example: Top-left angle on the first line and top-left angle on the second line.
- These are congruent when lines are parallel.

2. Alternate Interior Angles:
- Angles that are inside the two lines but on opposite sides of the transversal.
- They are congruent.

3. Alternate Exterior Angles:
- Angles that are outside the two lines but on opposite sides of the transversal.
- Also congruent.

4. Same-Side Interior Angles:
- Angles that are inside the two lines and on the same side of the transversal.
- These are supplementary (add up to 180°).

5. Same-Side Exterior Angles:
- Angles that are outside the two lines and on the same side of the transversal.
- Also supplementary.

6. Vertical Angles:
- Angles opposite each other when two lines intersect.
- Always congruent, regardless of parallel lines.

🔎 How to Solve Each Diagram:

For each diagram:
1. Look at the two labeled angles.
2. Determine their positions relative to:
- The two parallel lines (inside/outside)
- The transversal (left/right, same/opposite side)
3. Match the description to the correct angle pair name.

📌 Example:

Suppose a diagram shows:
- Angle 1 is above the top line, on the left side of the transversal
- Angle 5 is above the bottom line, on the left side of the transversal

➡️ This is a corresponding angle pair.

Another example:
- Angle 3 is inside, right side of transversal
- Angle 6 is inside, left side of transversal

➡️ This is alternate interior angles.

If you can describe the diagrams (e.g., “top-left diagram shows angles 1 and 5”), I can give you the exact classifications for each box.

Alternatively, if you'd like, I can generate a completed version of this worksheet with explanations for typical configurations.
