The given image shows two angles labeled as 3 and 7 formed by two parallel lines intersected by a transversal. To classify this pair of angles:

• Angle 3 is on the top-left side of the intersection, and
• Angle 7 is on the bottom-right side, located across the transversal but outside the parallel lines.

These two angles are on opposite sides of the transversal and are both exterior to the parallel lines, meaning they are alternate exterior angles.

So, the correct classification is:

• Alternate exterior angles

Would you like further explanation or clarification?

Here are 5 related questions to explore further:

1. What are corresponding angles in a transversal?
2. How can we identify alternate interior angles?
3. How do consecutive interior angles differ from alternate exterior angles?
4. Why are alternate exterior angles always congruent when lines are parallel?
5. Can you describe the properties of transversal angles for non-parallel lines?

Tip: When two parallel lines are cut by a transversal, alternate exterior angles are congruent (equal in measure).
