To determine the relationship between angle 5 and angle 1 when an inclined transversal intersects two vertical parallel lines M and N, we can analyze their positions.
- Angle 1 is located at the top left section around the intersection of line M.
- Angle 5 is located at the top left section around the intersection of line N.
Given the configuration, angles 1 and 5 are on the same side of the transversal and within different parallel lines. Therefore, they occupy the same relative position with respect to their respective intersections.
The correct relationship between angles 5 and 1 is that they are corresponding angles.
So, the answer is:
corresponding angles.
