To classify the pairs of angles you've provided, we need to determine if they represent alternate interior angles, alternate exterior angles, same side interior angles, corresponding angles, vertical angles, or if they have no relationship. However, it looks like the pairs you listed are incomplete as they don't provide context like a transversal or specific lines.
Assuming these pairs relate to angles formed by a transversal cutting through two parallel lines, we classify them as follows:
- Alternate Interior Angles: Angles that are on opposite sides of the transversal and inside the two lines.
- Alternate Exterior Angles: Angles that are on opposite sides of the transversal and outside the two lines.
- Same Side Interior Angles: Angles that are on the same side of the transversal and inside the two lines.
- Corresponding Angles: Angles that are in the same position relative to the lines and the transversal.
- Vertical Angles: Angles that are opposite each other when two lines intersect.
Without specific context or diagrams, it's difficult to apply the terms to the pairs you've provided. If these angles refer to their positions based on a diagram or a figure, please provide that context for accurate classification. Otherwise, if this is a theoretical question based solely on pairs of angles given as <13, <2, etc., that's not enough information to determine their relationships. Please clarify or provide additional information!
