Question

give a pair of alternate exterior angles, a pair of alternate interior angles, and a pair of corresponding angles.
(a) alternate exterior angles:
∠□ and ∠□
(b) alternate interior angles:
∠□ and ∠□
(c) corresponding angles:
∠□ and ∠□

Explanation:

Step1: Recall Angle Definitions

• Alternate Exterior Angles: Angles outside the two lines, on opposite sides of the transversal. For lines \(a, b\) (parallel, assumed) and transversal \(m\), \(\angle 1\) and \(\angle 8\) (or \(\angle 2\) and \(\angle 7\)) fit. Let's take \(\angle 1\) and \(\angle 8\): \(\angle 1\) is outside \(a,b\) (above \(a\), left of \(m\)), \(\angle 8\) is outside \(a,b\) (below \(b\), left of \(m\)), opposite sides of \(m\).
• Alternate Interior Angles: Angles inside the two lines, on opposite sides of the transversal. \(\angle 3\) and \(\angle 5\) (or \(\angle 4\) and \(\angle 6\)): \(\angle 3\) is inside \(a,b\) (between \(a,b\), right of \(m\)), \(\angle 5\) is inside \(a,b\) (between \(a,b\), left of \(m\)), opposite sides of \(m\).
• Corresponding Angles: Angles in the same relative position at each intersection. \(\angle 1\) and \(\angle 5\) (or \(\angle 2\) and \(\angle 6\), \(\angle 3\) and \(\angle 7\), \(\angle 4\) and \(\angle 8\)): \(\angle 1\) and \(\angle 5\) are both top - left at their intersections.

Step2: Identify Each Pair

• (a) Alternate Exterior Angles: \(\angle 1\) and \(\angle 8\) (or \(\angle 2\) and \(\angle 7\)). Let's use \(\angle 1\) and \(\angle 8\).
• (b) Alternate Interior Angles: \(\angle 3\) and \(\angle 5\) (or \(\angle 4\) and \(\angle 6\)). Let's use \(\angle 3\) and \(\angle 5\).
• (c) Corresponding Angles: \(\angle 1\) and \(\angle 5\) (or other valid pairs like \(\angle 2\) and \(\angle 6\)). Let's use \(\angle 2\) and \(\angle 6\).

Answer:

(a) Alternate exterior angles: \(\angle 1\) and \(\angle 8\) (or \(\angle 2\) and \(\angle 7\))
(b) Alternate interior angles: \(\angle 3\) and \(\angle 5\) (or \(\angle 4\) and \(\angle 6\))
(c) Corresponding angles: \(\angle 2\) and \(\angle 6\) (or \(\angle 1\) and \(\angle 5\), \(\angle 3\) and \(\angle 7\), \(\angle 4\) and \(\angle 8\))

(Note: Any valid pair for each category is acceptable. The above are examples based on standard angle - relationship definitions for parallel lines cut by a transversal.)
