To determine the relationship between angle 5 and angle 1 formed when parallel lines are cut by a transversal, we can analyze their positions.
If angle 1 and angle 5 are located on opposite sides of the transversal and between the two parallel lines, then they are called alternate interior angles.
If angle 1 and angle 5 are located on the same side of the transversal, they do not represent any of the listed relationships.
However, if they meet the criteria for alternate interior angles, then the correct answer is:
- alternate interior angles
If you can provide their positions regarding the parallel lines and the transversal, I can confirm the answer.
