To determine the relationship between angle 6 and angle 7, we can analyze their positions in relation to the two parallel lines (M and N) and the transversal.
- Angle 6 is on the upper part of line N, while angle 7 is on the lower part of line N.
- Angles 6 and 7 are inside the parallel lines (M and N).
According to the properties of angles formed by a transversal and parallel lines:
- Corresponding angles are on the same side of the transversal and are in corresponding positions relative to the parallel lines.
- Alternate interior angles are on opposite sides of the transversal and inside the parallel lines.
Since angle 6 and angle 7 are on opposite sides of the transversal and inside the parallel lines, they are considered alternate interior angles.
Therefore, the correct answer is:
alternate interior angles
