To determine the relationship between angle 6 and angle 7, we should consider their positions relative to the two parallel lines (M and N) and the transversal.
- Angle 6 is located on the inside of the transversal and to the right of line N.
- Angle 7 is located directly below angle 6 and is also between the two parallel lines.
Since both angles are on opposite sides of the transversal and between the two parallel lines, they are classified as alternate interior angles.
Thus, the correct response is:
alternate interior angles
