The complete statements are:
- Angles 1 and 5 are congruent because they are corresponding angles.
- Angles 4 and 6 are congruent because they are alternate interior angles.
How to determine the relationship between the angles
Angles 1 and 5
From the diagram, the relationship between angles 1 and 5 is that:
The angles are corresponding angles
In the geometry of straight lines, corresponding angles are congruent.
Hence, angles 1 and 5 are congruent
Angles 4 and 6
