Final answer:
Without a visual representation or further context, it's impossible to determine the relationship between <1 and <5 among the four options. We'd need more information or a diagram to give an accurate answer.
Step-by-step explanation:
In the context of angles, the relationship between <1 and <5 depends on their position relative to each other. The given options are corresponding angles, supplementary angles, alternate interior angles, and alternate exterior angles. Considering the information provided, it is not sufficient to determine the precise relationship without a visual representation of these angles. Supplementary angles are two angles whose sum is exactly 180°, whereas corresponding angles occur when two lines are crossed by another line (the transversal). Alternate interior angles are equal when two lines are parallel and a transversal cuts across them, also alternate exterior angles are equal under the same circumstances but are located outside the lines. The references to a 270° angle and angles being perpendicular indicate 90° angles, which do not directly match the options provided. Therefore, with the information given, an accurate relationship cannot be determined for <1 and <5 and the student may need to provide additional context or a diagram.
