To determine the relationship between angle 3 and angle 6 when comparing their positions concerning the two vertical parallel lines (M and N) and the inclined transversal, we can analyze their locations:
- Angle 3 is located at the intersection of the transversal and line M.
- Angle 6 is located at the intersection of the transversal and line N.
Since angle 3 and angle 6 are both formed by the transversal but lie on opposite sides of the transversal, specifically one on each of the parallel lines and in opposite positions relative to the transversal, angle 3 and angle 6 are corresponding angles.
Thus, the relationship between angle 3 and angle 6 is:
corresponding angles.
