Question

1. same - side interior
2. corresponding
3. alternate exterior

Explanation:

Step1: Identify same - side interior angles

Same - side interior angles are on the same side of the transversal and inside the two lines. For the given figure, $\angle2$ and $\angle5$ are same - side interior angles.

Step2: Identify corresponding angles

Corresponding angles are in the same relative position with respect to the transversal and the two lines. $\angle1$ and $\angle5$ are corresponding angles.

Step3: Identify alternate exterior angles

Alternate exterior angles are on opposite sides of the transversal and outside the two lines. $\angle3$ and $\angle7$ are alternate exterior angles.

Answer:

1. $\angle2$ and $\angle5$
2. $\angle1$ and $\angle5$
3. $\angle3$ and $\angle7$
