3-Parallel Lines and Transversals - Free Printable

To solve the problem of identifying each pair of angles as corresponding, alternate interior, alternate exterior, or consecutive interior, we need to analyze the relationships between the angles formed by a transversal intersecting two parallel lines. Let's go through each diagram step by step.

Key Definitions:

1. Corresponding Angles: Angles that are in the same relative position at each intersection.
2. Alternate Interior Angles: Angles that lie on opposite sides of the transversal and between the two parallel lines.
3. Alternate Exterior Angles: Angles that lie on opposite sides of the transversal and outside the two parallel lines.
4. Consecutive Interior Angles (Same-Side Interior Angles): Angles that lie on the same side of the transversal and between the two parallel lines.

Analysis of Each Diagram:

#### 1)
- The angles marked are in the same relative position at each intersection.
- Type: Corresponding Angles

#### 2)
- The angles marked are on opposite sides of the transversal and outside the two parallel lines.
- Type: Alternate Exterior Angles

#### 3)
- The angles marked are on the same side of the transversal and between the two parallel lines.
- Type: Consecutive Interior Angles

#### 4)
- The angles marked are on opposite sides of the transversal and between the two parallel lines.
- Type: Alternate Interior Angles

#### 5)
- The angles marked are in the same relative position at each intersection.
- Type: Corresponding Angles

#### 6)
- The angles marked are on opposite sides of the transversal and outside the two parallel lines.
- Type: Alternate Exterior Angles

#### 7)
- There are multiple pairs of angles here. Let's focus on the specific pair marked:
- The angles marked are on opposite sides of the transversal and between the two parallel lines.
- Type: Alternate Interior Angles

#### 8)
- There are multiple pairs of angles here. Let's focus on the specific pair marked:
- The angles marked are on the same side of the transversal and between the two parallel lines.
- Type: Consecutive Interior Angles

Final Answer:

\[
\boxed{
\begin{array}{ll}
1) & \text{Corresponding Angles} \\
2) & \text{Alternate Exterior Angles} \\
3) & \text{Consecutive Interior Angles} \\
4) & \text{Alternate Interior Angles} \\
5) & \text{Corresponding Angles} \\
6) & \text{Alternate Exterior Angles} \\
7) & \text{Alternate Interior Angles} \\
8) & \text{Consecutive Interior Angles} \\
\end{array}
}
